A dense canopy of tropical plants gives this stylish modern garden a lush and jungly feel. Owners Simon Bennett and Laura Holmes treat us to a tour
This bright, jungly garden has a secluded feel, with leafy palms and banana plants creating intimate spaces filled with exotic-looking flowers. “We’d just finished converting the barn on my parents’ farm when we started work on the garden about 10 years ago,” says owner Simon Bennett, who lives here with his partner Laura Holmes.
“We had no experience, but we knew that we wanted plants to tower overhead on different levels to create a lush planting scheme to look out on. Exotics seemed to be the answer and, after clearing the ground of grass and rubble, we started with trachycarpus, tree ferns and a couple of cordylines. Sadly we lost a lot of them that winter and became a bit disheartened…”
The couple really got into their stride in 2012, after spending time visiting exotic gardens such as Tresco Abbey and Lamorran House in Cornwall. “We were inspired by the dense plantings of palms there, and also by Will Giles’ exotic garden in Norfolk, which showed us what could be grown outdoors in the British climate.
“We started off in the walled area next to the kitchen, where we chose large-leaved and tall-growing plants for maximum impact, such as bananas Musa basjoo and Ensete ventricosum ‘Maurelii’, brugmansia (angel’s trumpets), butia palms and tetrapanax, all bought online from specialist nurseries.
“Many beds are raised to give the plants extra height,” says Simon. “We invested in more mature specimens to create the towering canopy we wanted more quickly.
“We then filled in the lower levels with plants that have exotic-looking flowers and leaves, such as Begonia rex and cane-stem begonias, anthuriums, echiums, hedychiums, eucomis and cannas.”
Potted houseplants are incorporated into the summer displays. “These include Swiss cheese plants, staghorn ferns, spider plants and tradescantias,” says Simon. “Bromeliads and air plants are attached to tree trunks.”
The couple soon extended their exotic planting beyond the kitchen garden. “As we grew in confidence and experience, we dug over more of the garden to create fresh planting areas,” says Simon. “These are connected by winding gravel paths and lead to a jungle hut – our covered outdoor seating and dining area – and also to a large greenhouse, predominantly used to overwinter our more tender plants. We got special planning permission for the greenhouse, because it had to be really tall (4m/13ft) to accommodate some of our larger specimens.”
Tender plants are moved under cover towards the end of October, with Simon keeping a careful eye on the weather forecast for frosts. “Our greenhouse is heated to 5C (41F) to ward off frost damage. The plants stay in there until May when we plant everything out again.
“Even so, I’ve often been surprised how many can survive outside. Our tree ferns have remained evergreen for the past four years and our Musa basjoo bananas are mainly unprotected, although I did wrap them up with fleece and straw when the ‘Beast from the East’ struck in 2017.”
Tetrapanax now tower overhead and the eucomis, hedychiums and tradescantia all survive winter outdoors, with echiums naturally seeding around.
“We spend most of our summers watering, feeding, deadheading, staking, tying in and moving the potted displays around as new plants come into flower,” says Simon. “We also do a lot of propagating for our plant sales bench on open days. It’s labour intensive, but we love it!”

Choose bee-pleasing blush and blue flowers for a soothing end of summer treat, says Helen Billiald
Choose plants with pollinators in mind and you’ll soon be visited by those ever-busy butterflies, hoverflies and bees, whose tumbling flight is so hypnotic to watch.
This blush-and-blue planting of herbaceous perennials has huge pollinator appeal, while also winning points for serious longevity, both in flower and the skeletons left behind. Find the plants a sunny site then sit back and watch the show.
Just make sure you pay attention to the conditions – monarda, phlox and echinacea prefer moist, humus-rich soil with sufficient drainage to prevent prolonged winter wet, while the agastache and hylotelephium require a well-drained soil.
PLANTS TO USE
Echinacea purpurea Pink-petalled coneflower with dusky orange centres. A pollinator pleaser, flowering July-Sept. Finches love the seedheads. H90cm (3ft) S60cm (2ft)
Phlox paniculata ‘Le Mahdi’ Large-flowered violet-purple phlox with scented panicles July-Sept. Needs moist but well-drained soil. H90cm (3ft) S60cm (2ft)
Agastache ‘Blackadder’ Vertical spikes of violet-blue flowers July-Oct, adored by bees. Strongly fragrant foliage. Needs good winter drainage. H90cm (3ft) S35cm (14in)
Monarda ‘Vintage Wine’ Whorls of magenta to berry-red flowers on top of sturdy stems July-Oct. Excellent winter silhouettes. Good bee pleasers. H90cm (3ft) S30cm (12in)
Persicaria alpina Statuesque perennial with a haze of frothy white flowers gradually tinged with pink Aug-Sept. Undemanding, but needs room to spread. H1.8m (6ft) S1.5m (5ft)
Hylotelephium ‘Veluwse Wakel’ Grey-green fleshy foliage and pink-purple starry flowers July-Sept that look like insect landing pads. H75cm (2½ft) S45cm (18in)
HOW TO PLANT YOUR BORDER
Clear the site, digging out perennial weeds and breaking up compacted ground, then work in plenty of well-rotted organic matter across the area. This improves the moisture-retaining properties of lighter soils, while opening up heavier ones and helps to balance the needs of the phlox, monarda and echinacea (adequate moisture in summer, good drainage in winter) with those of the agastache and hylotelephium (well-drained soil). Add horticultural grit to targeted areas on very heavy ground.
1 Establish the persicaria
This statuesque white-flowered perennial needs a generous amount of space, so establish it first as the backdrop of the border. Your potted youngster may appear puny but if you lay a 1.5m (5ft) bamboo cane down, pivoted at its centre, you’ll get an idea of elbow room required.
In growth it’s undemanding and will cope with some shade. Cut back established plants in February or March. Despite their size, they’re well-behaved clumping plants rather than invasive spreaders. You might need a saw when it comes to dividing them.
2 Add the rest of the perennials
Water the remaining perennials in their pots, then arrange them across the border. Allow plants enough elbow room for a couple of year’s growth and tuck the phlox towards the back to hide its less attractive lower legs. Once you’ve identified the area for the agastache and hylotelephium, check that their section has adequate drainage, lightening ground with further grit and organic matter if required.
Having confirmed the layout, begin planting, forking in further compost to each hole as you work and finishing with a layer of well-rotted organic matter as mulch. Keep an eye out for slugs and snails and keep watered during dry spells.
3 Maintain the border
Mildew can be problematic with these perennials, causing white powdery patches to develop across foliage. Your first line of defence is to grow plants well, watering deeply during dry spells and resisting overcrowding when you plant. Prune away infected foliage promptly, or in severe cases cut back the entire plant hard and water well for regrowth.
Deadhead to keep flowers coming but stop in early autumn to leave flowers in place for sculptural winter seedheads to catch those elusive hoar frosts. Clear away the phlox in late autumn but leave the rest of the sun-bleached stems until February or March. Then, cut back and mulch using well-rotted organic matter.
Lift and divide plants every three years; skip this step and the display will gradually diminish. Most of the plants are content with either an autumn or spring split (see p30), but the agastache and monarda need to wait until spring. When splitting keep only the healthiest and most vigorous sections, usually at the outer edges of the clump, and improve the border soil before replanting. Monardas in particular have a habit of dying at the centre and moving out into new areas where you don’t necessarily wish them to be.
If you struggle with agastache failing to survive winter (‘Blackadder’ is one of the most reliable), practise taking semi-ripe cuttings as insurance in late summer, and overwinter them somewhere sheltered and frost-free ready for planting out next spring.
This sloping S-shaped plot is full of exotic flowers and jungly intrigue. Owners Juli Madwick and Mike Ford show us around
This quirky, exotic garden in Nottinghamshire is a tranquil haven filled with towering palms and big-leaved banana plants. It’s hard to believe the south-facing plot offers fine views over a classic English landscape and the crenellated ramparts of Belvoir Castle!
“It’s easy to be transported somewhere far more exotic,” says owner Julie Madgwick, who gardens here with her builder husband Mike Ford. “The garden looks fantastic in late summer but we have faced up to some challenges along the way.”
The couple moved here more than 20 years ago, in 1996. “The house was empty and run-down when we moved in, so we had to address that first,” explains Julia. “Then we turned our attention to the garden and discovered the soil was solid clay – you could make teapots out of it! We began by clearing away a dilapidated pigsty, aviary and multitudes of weeds. We kept some of the existing roses and fruit trees and put in a few different plants, but at the time we didn’t have much sense of design direction.
“Inspiration finally struck when we visited the exotic garden of the late Will Giles, who created a subtropical garden in Norwich, on a similar sloping, south-facing plot like ours,” says Julia. “Initially I was told I couldn’t grow exotic plants in heavy clay, but that was like showing a red rag to a bull! I was determined to turn my half-acre garden into a tropical paradise like Will’s. But it certainly took a lot of effort to make the soil more workable.
“We started off by rotavating the soil and clearing some of it into a mound in the front garden, where we’ve planted cannas, cordylines, hemerocallis and bananas. We incorporated bulk loads of horse manure into the garden beds – and continue to do so every year – topped with a compost mulch. Now it’s beautiful soil; very rich and moisture retentive.”
The planting has evolved as they’ve gone along. “With each new planting area, we’ll start with an architectural plant in the middle, such as a tetrapanax or alocasia, to give height and structure,” explains Julia. “Then we’ll surround it with other plants with big leaves or tropical-coloured flowers, graduating the height down to ground level.
“Fiery-coloured fuchsias, begonias, crocosmias, dahlias, alstroemaria and pelargoniums all work really well,” says Julia. “We plunge-plant many more tender species, still in their containers, among the more hardy ones so they can be lifted more easily at the end of the season for overwintering.
“Splashes of cool blue agapanthus and salvia offer a bold colour contrast. This creates a truly lush, tropical look. I never want to see bare soil; it spoils the effect completely.”
For foliage interest there’s colourful coleus. “They’re wonderful foliage plants and are really easy to grow from seed,” says Julia. “We also use alocasia; you can buy their roots really cheaply from Indian supermarkets to grow on. They come in all sorts of colourful leaf patterns.”
To keep a sense of order throughout the garden, Julia has a good tip: “Keep the lawn mown with tidy edges, and sweep the paths to provide a neat framework for the exuberant planting.”
Greenhouses are essential to overwinter the more tender exotics. “We now have four, each with its own name so we know which one we’re talking about!” laughs Julia. “For instance, ‘Pigsty’ is where the messy work is done; ‘Julia’s Room’ contains my potting bench; and ‘The Dome’ is where we keep our permanent display of plants, together with a wood-burning stove. It’s a great place to enjoy a bottle of wine in winter.”
The geodesic dome took six weeks to build. “We bought it secondhand and collected it as a series of glass panels, with no instructions,” says Julia. “There were nine different sizes of glass and 11 different-sized metal struts, and they only fitted together one particular way!”
The couple grow many of their plants from seed and cuttings. “We also sell them on our National Garden Scheme open days,” says Julia. “Last year our stocks were boosted after a trip to a cactus nursery. We discovered it was closing down that same day, so we came away with everything they had left. We even returned with a mini-digger to rescue the two mature palm trees at the entrance!”
Water is a key part of the garden’s aesthetic. “When we unearthed an old millstone and water tank, Mike used them to create a trickling fountain in the front garden,” says Julia. “This circulates water along a manmade stream bed that snakes right through the garden, widening out into ponds along the way. We’ve created a decked pier supported by large, rustic gateposts and telegraph poles as a viewing platform. We like bold, iconic structures – it’s certainly not a twee garden. The neighbours must wonder what on earth we’re going to do next!”

As the days get shorter, much of the garden slips into a winter slumber. Some herbaceous perennials retreat below ground, the last annuals succumb to frost and dormant deciduous shrubs and trees shed a carpet of colourful leaves. It can feel like the finale to the gardening year, and time to hunker down indoors until spring.
However, a winter garden can be a beautiful, enchanting place. Chosen carefully, plants can raise the spirits with unexpected flowers and scent, providing you with a colourful scene to look out onto from the warmth of indoors.
A heavy frost can lure you outside to marvel at the intricate detail of cobwebs and seedheads, the luminescent quality of jewel-like berries and the crazed patterns trapped in a frozen bird bath. All these seasonal treats ease the journey through the bleakest months.
Flowers may be few and far between, but foliage, stems, berries and bark can all help to bring colour, shape and texture to your garden. Even if space is limited, you can distil these elements into winter container displays using dwarf shrubs and conifers, evergreen ferns and grasses mixed with cheerful winter bedding.

This delightful garden in Lincolnshire is enjoying a renaissance, with exciting new ideas that have revitalised its Tudor template
Once described by US President Franklin D Roosevelt as “a dream of Nirvana… almost too good to be true” Easton Walled gardens is a romantic garden that has survived its fair share of adversity. This historic rural estate in the idyllic Lincolnshire countryside has been owned by the Cholmeley family for more than 400 years. But, like so many of our grand country estates, Easton felt the impact of two world wars and by the end of the 20th century, the gardens were in such a parlous state they were placed on English Heritage’s ‘At Risk’ register.
In Easton’s case the house and grounds were requisitioned by the military, but the soldiers billeted there showed little or no respect for the buildings, which suffered such extensive damage that the family never returned. In 1951 Easton Hall was demolished – the surviving stables, gatehouse and a handful of outbuildings are all that’s left of the original buildings – and the gardens were gradually consumed by self-sown trees, thickets of brambles and towering weeds.
In 2001, spurred into action at the prospect of the gardens being lost forever, the new owner Lady Ursula Cholmeley, with no budget, a few willing friends and family and limited machinery, embarked on a revival of the 12 acres of gardens. As the undergrowth was cleared the original Tudor and Jacobean layout of the gardens was uncovered, as were carpets of snowdrops that, once uncovered and exposed to light, have now spread to cover the riverbanks.
While much of the current layout follows the old Tudor design, Lady Cholmeley has incorporated contemporary ideas along with an overriding ethos that the gardens have to work in harmony with nature. Meadows and grasses feature strongly, not least because the garden lies on a limestone bedrock with barely any topsoil. Rather than fight against these conditions, Lady Cholmeley decided to encourage a rich diversity of meadow plants such as pasque flowers, scabious and cowslips.
In spring the Woodland Walk is dominated by two fabulous old trees – a horse chestnut and a black walnut – and is filled with exquisite epimediums, violets and hellebores.
The White Space is a traditional white planting scheme with a contemporary feel inspired by landscape designer Charles Jencks. Cosmic swirls are marked out with topiary box interplanted with white-flowered Cerastium tomentosum.
Sweet peas were one of the first plants to be grown in the garden when the restoration began in 2001. Since then they’ve become a firm favourite and can be found growing en masse in the cutting garden, otherwise known as ‘The Pickery’: a space filled in summer with dahlias, cosmos, zinnias, rudbeckias and salvias. The gardening team trial new varieties of sweet pea every year, selecting the best to grow on a larger scale the following year.
There’s a burgeoning orchard planted with local fruit cultivars and more unusual crops such as quince and greengages. The greenhouses and vegetable garden – long raised beds made from oak sleepers – brim with produce which keeps the café supplied with a delicious range of home-grown fruit and veg throughout summer and autumn.
Roses are planted in meadows – an unusual way of growing this classic flower. Advised by David Austin Roses, a variety of cultivars have been planted in the long grass, which creates a spectacular sight as blowsy blooms float above a sea of bleached-blonde grasses.
The terraced summer meadows cover a steep slope from the main garden down to the river. The flat sections are mown, but the slopes are left so that the grasses grow long creating an informal frothy appearance that contrasts with the formal flights of stone steps and topiary pyramids. Another quirky touch is the unexpected sight of life-size metal giraffes gazing out over the surrounding countryside.
The revival of the gardens and the wider estate will be a long process, but in a relatively short amount of time Easton Walled Gardens has been transformed into a wildlife-friendly space that manages to combine the best of old and new in garden design. *
Location: Easton, Grantham, Lincolnshire NG33 5AP
Open: Weds-Fri, Sun and Bank Holidays 11am-4pm until 28 Oct. Open for one week in February for snowdrops.

Let dazzling dahlias and Verbena bonariensis brighten up your borders this month, says Helen Billiald
This planting scheme is inspired by the exotic garden at Great Dixter. It’s 25 years since Christopher Lloyd ripped out the old rose garden in order to create this exotic wonderland. Together with his gardening protégé, Fergus Garrett, they converted the once-formal space into a fantasy garden filled with colourful, jungly plants like this stunning combination of dahlias, verbena and ipomoea. The resulting late summer and autumn profusion inspired a seismic shift in planting styles across the country whose influence continues to resonate today.
Choose the right plants
Unflinchingly violet-pink dahlia with semi-double dark centred flowers against a backdrop of inky leaves. H and S 90cm (3ft)
Grey-blue lance shaped leaves emphasise this canna’s salmon pink flowers. H1.5m (5ft) S50cm (20in)
Little clusters of purple-lilac flowers on stiff branching stems, June to October. Airy look makes it a wonderful ‘threader’ through other plants. H1.8m (6ft) S45cm (18in)
Spanish flag is a fast-growing tender twining climber that’s treated as an annual in this country. Its tubular flowers mature from red to creamy yellow. Flowers from July to the frosts. H2.4m (8ft)
Pennisetum advena ‘Rubrum’
Dark red strap-like foliage and arching bottle-brush flowers that mature from rusty red to brown. Dubious hardiness, lift to overwinter. H90cm (3ft) S60cm (2ft)
Large bold foliage plant with palmate leaves and white flowers in late autumn. Needs space, sends out suckers and not hardy for everyone. Typically, H2-3m (6-8ft) S2m (6ft 6in)
If you’re after a tip-top display you really want to spoil this planting. Give it your best, sunniest site sheltered from strong winds and be prepared to seriously improve your soil to ensure fertile growing conditions. Annual mulching with well-rotted organic matter as well as digging in further material at every planting will also help. Be prepared to water deeply during prolonged dry spells.
1. Order the dahlia and canna
Order the dahlia tubers and the canna rhizomes now and you’ll be able to forget about them until they arrive in the post next February or March. Pot them up and grow them on in a frost free greenhouse before planting out in late May. If you want to increase your stock then take cuttings from stout newly emerged shoots. Watch out for slugs and snails which can decimate young foliage.
‘Fascination’ is a relatively short cultivar but it’s still worth putting in a cane when you plant so that you have the option to support shoots with twine if needed. Deadhead every time you pass to keep the display coming. Once plants have turned black from the first frosts you can either cut them back and dig up the tubers to store in barely damp old potting compost in a frost free shed, or leave them in situ covered with a protective dry mulch.
Unless you live in a very sheltered part of the country and on free-draining soil, it’s not worth the risk of leaving plants in the ground over winter, even with a protective mulch. Instead, wait for the first frosts then cut back plants and lift as a single clump to store surrounded by old potting compost kept damp in a frost-free shed. Next spring large plants can be divided and potted up, making sure each new section has several growing buds.
2. Sow the verbena
Verbena bonariensis is a doddle to grow from seed, you just need to give them an early start. Sow under cover in March using a warm windowsill or heated propagator at around 20C (68F).
A more expensive option is to pick up young plants in late spring. Once they’re established you’ll find they self-sow and seedlings start to pop up around the garden often in unusual yet welcome places like paving cracks or sections of gravel.
Plants are short-lived perennials and overwinter best on well-drained soil. A dry winter mulch helps get them through the coldest spells. Resist cutting back the top growth until new shoots are growing the following spring.
3. Sow the ipomoea
Sow seeds in mid-April to May in the greenhouse. Seeds are large and easy to handle with good germination rates so sow one seed to a pot and use a propagator to maintain a cosy temperature (around 21C/70F). Soaking or nicking seed isn’t essential. Pot on before planting out in early June when nights should have warmed up.
These plants will cope with shade as well as sunshine, just avoid too much nitrogen in the planting site or you’ll run the risk of over enthusiastic foliage with little in the way of flowers. They’re brilliant at rambling right through a planting, often travelling in unexpected directions.
4. Add the pennisetum
Give this tactile grass a front-of-border position so you can stroke its arching bottle-brush flowers as you pass. ‘Rubrum’ is sterile so there’s no chance of sourcing this plant from seed. Instead order plants from a specialist nursery ready for delivery in May or look out for them at your local garden centre. Youngsters are best planted out after all risk of frost.
Dig up plants once frosts are threatened and move them undercover into a frost-free greenhouse. Lift them as a single large clump, cut back the top growth by half and place in a large container, filling in any gaps with old potting compost: you’re not trying to encourage new growth now. Water sparingly over winter then in spring divide into smaller clumps and pot up in fresh compost ready to plant out in late May.
5. Establish the tetrapanax
Specialist nurseries will be your best chance of tracking down young tetrapanax. Plant out in early June allowing plenty of space from the start and further improve the ground with well-rotted organic matter – it prefers a well-drained site.
In future years, severe winters will dictate how much top growth survives. Even if it’s cut back right to the ground by frost it will regrow from its roots the following year. You might also choose to coppice plants right back in early spring to encourage lots of low shrubby growth rather than a taller trunk. Remove unwanted suckers as they appear in spring: you can always pot them up as gifts for jungle-loving friends.
Bees will love this nectar-rich meadow filled with purple monardas and orange heleniums. We humans can enjoy it for its vibrant flower shapes and colours, too.
Drifts of monarda ‘Scorpion’ (a cultivar bred by Dutch plantsman Piet Oudolf) have been combined with blocks of orange-red heleniums, their petal skirts splayed out like flying pinwheels.
Softening the colour contrast are spires of white Veronicastrum virginicum ‘Album’, rising like bubbles in a fizzy drink.
To round off the planting scheme we’d add in some Verbena hastata, white liatris and a bold annual rudbeckia, whose orange daisy flowers echo the helenium.
This pretty border has a wild-and-free simplicity, featuring woodland and countryside natives, such as foxgloves (Digitalis purpurea), feverfew (Tanacetum parthenium) and common valerian (Valeriana officinalis).
Alliums and nepeta offer some contrasting blue flower forms – balls and spires – underpinned by a frothy haze of yellow lady’s mantle, Alchemilla mollis. This easy-to-grow perennial will happily self-sow and makes a picturesque path edger with its scallop-shaped ruffle of foliage. You could add in a soft pink dog rose for the full country garden effect. Alliums need full sun, the foxgloves part shade and the rest will thrive in sun or part shade.
COMBINE THESE PLANTS
Large purple heads of flowers June-July. Rich, well-drained soil. H1.2m (4ft) S25cm (10in)
Dome-shaped umbels on tall branching stems June-Aug. H1.5m (5ft) S45cm (18in)
Shade-loving woodland flowers June-July, loved by bees. H2m (6½ft) S60cm (2ft)

Daisy-like flowers June-Sept. Bushy perennial herb good for bees. H60cm (2ft) S30cm (12in)
This Dorset garden is an atmospheric showcase for grasses in autumn, says Louise Curley
For many gardens November is the tipping point into hibernation as flowers and foliage fade. At Knoll Gardens in Dorset it’s a different story. Home to thousands of grasses, the renowned naturalistic planting is reaching its crescendo right now. The four-acre garden had its beginnings in the early 1970s when the first nursery on the site was established on a carrot field and a scrubby patch of land. In 1994 Neil Lucas came to the garden and nursery and has since established one of the country’s most extensive collections of grasses.
‘Right plant, right place’ is very much the approach at Knoll, where planting is dictated by the soil and climate, rather than trying to grow unsuitable plants that will never thrive. The garden is also the perfect showcase for plants on sale in its award-winning nursery, and offers visitors the chance to see these plants growing in a garden setting, with inspiring ideas for planting combinations.
Although primarily known for its grasses, Knoll used to be a private botanic garden and as a result it also has an impressive range of trees and shrubs. The delicate white, bell-shaped blooms of the Australian snowdrop tree (black sassafras) announce the arrival of spring as their delicate scent fills the air. Summer highlights include herbaceous perennials and hydrangeas, but it’s late summer when Knoll hits its stride, with herbaceous perennials such as sedums, asters and the wafty stems of Verbena bonariensis forming drifts of colour.
Spectacular autumn hues from trees such as Gingko biloba and shrubs like Hydrangea quercifolia light up the gardens with a fiery glow. The collection of spindle trees (euonymus), which thrive on the free-draining sandy soil, put on an eye-catching display of vivid crimson and scarlet. Impressive specimen trees include one of the best willow oaks in the country, cork oaks and a collection of magnificent eucalyptus.
The Dragon Garden consisted of bedding plants, formal hedges and lawn when owner Neil Lucas first came to the site more than 20 years ago. It’s now been transformed so that a single path weaves through a swathe of grasses and perennials, which create a tall meadow effect. At this time of year, late autumn sunshine enhances the warm browns, golden honey and bleached blonde tones of the grasses and early morning frosts highlight the structural shapes and seedheads.
The vast range of grasses includes low-growing pennisetums that tumble over paths to towering miscanthus and calamagrostis. One of the most effective planting combinations here is the native grass Molinia caerulea planted in drifts along with perennials such as persicaria, scabious and sanguisorba.
Although grasses are mostly associated with large-scale naturalistic planting schemes, such as those created by Dutch plantsman Piet Oudolf, smaller easy-care beds have been created at Knoll to show that they can be used in a more modestly sized plot.
Knoll Gardens is an impressive place to visit whatever the season, but at this time of year, with the seedheads and skeletons of the grasses and perennials catching the sunlight, it’s a place that shows how there can be beauty even in the dying embers of a garden.
Five minutes with... Knoll Gardens' owner Neil Lucas
Neil Lucas has been the owner of Dorset-based Knoll Gardens and its award-winning nursery since 1994. His passion and knowledge for a naturalistic planting style and ornamental grasses has led to multiple gold medals from RHS Chelsea
Q. How did you come to be at Knoll? I was working and living down in Devon, and we saw an advert that said the gardens were for sale. So we – my mum, dad and myself – decided to buy it. Horticulture has always been important in the family. My grandfather, in particular, was very much into plants and especially his delphiniums. Some of my earliest memories come from summer holidays with him in his garden and watching him exhibit at the RHS Halls in London.
Q. How big is the team? We have one full-time gardener, so we practice what we preach with low maintenance. We do also have half a dozen or so volunteers who come in on a Friday morning.
Q. What are the main seasonal jobs? We’re a late-season garden, so we peak in interest in the second half of the year. This means we cut down in early to mid-spring and do a spring clean preparing the borders, doing any maintenance and mulching. We weed in summer and then do any structural projects later in the year.
Q. In November what are you working on? November is still our peak time in the garden, so we won’t be doing a lot to the borders. But what we do try and do before Christmas is to complete one or two planting jobs. If things haven’t worked so well, there’s a gap in a border or we’ve decided to do something in a different way, we’ll take up the plants, move them around and replant.
Q. Do you have a favourite part of the garden? This year I do rather love the Dragon Garden. We took out a hedge about a year or so ago and did a lot of new planting, so it’s much more expansive now. It’s a bit reminiscent of a prairie.
Q. What’s the most challenging aspect of your job? Running a small business is always highly demanding of personal time. Actually finding time to do all the necessary jobs and to be able to leave a little bit for the one or two jobs we might like to do, such as planting new areas, is always tricky.
Q. What’s the best bit of your job? Playing with plants, seeing new combinations and seeing them grow and develop. It’s a real thrill to see a plant that’s happy and successful and settled into the garden.
Q. Do you have any future projects that you’re planning to carry out? Our eucalyptus lawn is relatively old, the trees have got too big and are casting a lot of shade, so we’re going to redevelop that over the next few years, which will be quite a big project for us.

Want to create your own ‘Zen’ courtyard?
It's no wonder the Japanese style of gardening is so popular in Britain. It’s a style that can be adapted to suit even the smallest outdoor space and most of the plants are quite happy in our temperate, often drizzly climate. The preponderance of shade-lovers creates a soothing green palette too – the perfect antidote to our stressful lives, with seasonal highlights offered by delicate spring blossom and flamboyant acers in autumn.
Though the style is steeped in tradition and ancient symbolism, its simple, ‘less is more’ philosophy keeps it looking up to date. Modern urban gardeners will love the clean lines, emphasis on textures and overriding sense of calm.
Traditionally, Japanese gardens are miniature recreations of the natural landscape, with water represented by sand (raked into ripples), and rocks representing mountains such as Mount Horai. These two elements are the essential ‘yin and yang’ of the design and, in landscaping terms, are a good place to start.
Stone lanterns and water basins are further key ingredients. The water basin was traditionally a place to wash before taking tea at a traditional tea house.
Team elegant acer foliage with evergreen boxand choisyafor this bold oriental border
Autumn is a fabulous time to have acers in the garden. Their flamboyant colours, slow growth and elegant layers of branches make them a popular choice in even the smallest of courtyard gardens.
If you’re looking for partner plants to help their bonfire colours glow, it’s worth taking inspiration from the Orient. Japanese gardens have a serene atmosphere that comes in part from a calm, simplified plant palette – often just gentle greens and blues. These allow the vivid acers to take centre stage as their foliage changes colour.
Japanese maples (Acer palmatum) grow best with a bit of shade and shelter. Treat them as woodland edge or ‘understorey’ plants out of direct sun – a lightly shaded corner would be ideal.
All the shrubs here will pretty much look after themselves in time, making this an easy-care planting scheme perfect for a front garden, bringing you a sense of calm every time you arrive home as well as joy to passers-by.
THIS ELEGANT FORMAL garden is packed with colourful plants and inspiring artefacts. “Being former art teachers has definitely had an influence on how we created the garden,” says Barbara. “We’re both interested in architecture, travel and design history, and Marek is interested in classical history and its influence on architecture.”
The classical influence is revealed in the garden structures and ornaments. “There’s a pavilion with classical architrave and columns (now with mosaic inside), an elaborate red brick wall fountain, Pompeii-style frescos and decorative urns. Marek built all the architectural elements himself.”
The garden is a rectangular plot that Barbara says is large by London standards. “It was once part of a large estate that was subdivided into generous plots. The garden is where the manor’s orchard used to be and still contains old pear trees, now covered with scrambling roses ‘Kiftsgate’ and ‘Rambling Rector’.
“When we moved here 15 years ago the garden was simply a large lawn surrounded by established trees,” says Barbara. “I was keen to keep a large area of grass, so the first job was to set out the main feature of the garden – a small parterre – about three-quarters of the way down the lawn. I created lots of box topiary to go with it – pyramids, balls and cylinders – and planted a bay tree in the centre.”
The bay was a small standard 14 years ago, but it’s grown into a large tree. “It’s actually two trees tied together; over time they’ve grown into one another,” says Barbara. “We trimmed out the lower branches then let it come out in an umbrella shape at the top.”
The iron pagoda is a more recent introduction. “We often visit reclamation yards to hunt for architectural treasures and on one visit saw a similar but more expensive piece,” says Barbara. “It inspired us to search online to find something more affordable, and that’s how we found this one at a salvage yard in Suffolk. It was covered in rust and dismantled for transport so we had to piece it back together by hand.
“We guessed it would kind of fit, but when we put it up in situ over the parterre it’s brilliant – as if it was meant to be. I was thrilled because I’d seen ironwork against quite formal box up in Kensington and thought it looked really beautiful.”
Though Barbara initially wanted to keep the large formal lawn, she says she ‘weakened’ and decided to have more flowers instead. “I added two mirror-image beds in front of the parterre and filled them with soft purple and pink flowers that look so lovely in early summer,” she says. “These are followed by hot, bright late summer flowers such as heleniums and crocosmia, chosen by Marek. We’ve also created another bright flower bed nearer the house and filled it with trailing bedding plants. There’s a further formal raised pool behind the parterre, where we grow a huge gunnera flankedby two tall cypress-like conifers. We’ve planted it all symmetrically to go with the formal theme.”
The final few metres of the garden are more relaxed and shady, given over to plantings with a woodland feel. “This area is filled with moss, hostas and ferns,” says Barbara. “Though the garden is south facing, it backs on to a tree-lined railway embankment, which throws deep shade here. It’s a wonderful backdrop but at certain times of day it just doesn’t get any sun – it’s one of the difficult things about the garden.”
Barbara likes to experiment with planting styles and adores the variety offered by plants. “It’s been a challenge but I’ve really tried to stick to a theme. I just wish we had a bigger garden. Or, perhaps I need three!”
FOR SARAH BEART gardening has always been a family affair. Her garden in north Norfolk reflects a gardening talent that has been fine-tuned since childhood.
“My granddad used to grow sweet peas and when I was young I had my own small plot and little tools. Both my maternal grandparents’ fathers were head gardeners, so I’m sure it’s in the genes!” says Sarah.
Her great-grandfathers oversaw gardens on large estates in Norfolk, where Sarah and her family still live, in a small village near the market town of King’s Lynn. It’s a rural idyll complete with a 13th-century church that looks over the garden.
“Our house was the former rectory, where Admiral Lord Nelson’s second cousin once lived, as rector,” says Sarah. “When we moved in nine years ago, we found that our overgrown plot harboured a secret garden. Under the brambles and bindweed we uncovered the beds, planting areas and lovely old roses that a former gardener had created. We even found a pond. In fact it was all so overgrown that we didn’t discover a huge statue of an owl until three years later... I weeded and weeded and dug and dug, exploring the space gradually to see what other treasures were hidden in the undergrowth.”
Sarah’s exploring and digging revealed the bare bones of an excellent garden that, through a process of evolution, became the framework of the bright and charming cottage garden we see today – the perfect partner for Sarah’s historic cottage.
“The boundary is lined with tall trees, which give the garden a sense of seclusion and create shade,” she says. “I try to make a feature of the shady areas – for example one contains a 35m (115ft) long stumpery made from a local tree surgeon’s offcuts and filled with ferns and hostas.”
“I’ve also created a woodland walk containing the garden’s 64 trees, whereI’ve planted violets, primroses, thalictrum and Japanese anemones.”
To help organise the space, the large plot is divided into three distinct areas: the main garden with its dramatic herbaceous borders, sweeping lawns and pond; a gravel garden and rockery for sun-loving alpines; and a relaxed wild flower area that’s humming with bees and butterflies.
Throughout the garden are unusual elements to draw the eye. “The dovecote has been home to a flock of white doves since before we moved in, and we have a small group of bantam hens that roam free in the garden. The birds bring character to the garden too; they drink from the large pond and roost in our bay tree.”
The deep herbaceous borders are Sarah’s pride and joy. “I love cutting flowers for indoors, particularly traditional English flowers, which I like to paint in watercolours. I love the process of growing them from seed, cutting them and then painting them.”
Sarah has filled her deep flower beds with vibrant, but always well-co-ordinated, colours – yellows, pinks, reds and blues, softened with cool white flowers. They also provide cut blooms for Sarah’s mum, who’s a keen flower arranger.
Sarah has strung a rope swag through the main border. “It’s a lovely feature that adds height and, in places, makes a support for climbing roses. My grandmother used this technique in her garden and I always wanted to recreate it here.”
THERE'S BARELY A FLOWER in sight in Patrick de Nangle’s London garden. Instead this astounding urban jungle is packed with foliage plants and towering tree ferns, which is all the more astonishing when you consider the modest size of his compact back garden.
Patrick first saw tree ferns growing at some botanical gardens in Hawaii, but it wasn’t until a trip to Bali that he realised he wanted to grow them himself at home. “They’d planted tree ferns with moss underneath, and I decided to create something similar here,” says Patrick.
“I buy them direct from a specialist importer, Lyndon Osborn, who designed the fernery at the Royal College of Art. They arrive as stumps so I dig a hole 40cm (15in) wide, mix in some compost and bark chips then sit the stump on the ground. Then I put a stake beside it and tie it to the stake. The stump will take root and start growing in a few weeks.”
Patrick has chosen two main types of tree fern to vary the visual effect. “There’s the Australian Cyathea australis, which is seldom grown in the UK, and the more familiar Dicksonia antarctica. Cyathea australis has a scalier trunk than the dicksonia, and I prefer that textured look. My rarest specimens are the black tree fern Cyathea medullaris, the elegant Dicksonia squarrosa, and the Norfolk tree fern, Cyathea brownii, which is massive and grows to more than 30 metres (98ft).
“Tree ferns are like a sponge – they need lots of water. You have to water them once a week in summer. I spray the whole trunk then hold the hose over the top of the plant and count for 50 seconds! I also feed them every six weeks, with a special tree fern food, and fish, blood and bone.”
The garden was just a lawn, weeds and astraggly lilac shrub when Patrick arrived here 12 years ago. “Rather than have grass struggling under the trees I took up the lawn and planted mind your own business (Soleirolia soleirolii) instead,” he says. “It makes a fine green carpet of tiny leaves that helps to frame the tree ferns, making the garden feel much more jungly.”
Patrick planted the soleirolia at 45cm (18in) intervals around the garden. “Within a year all the plants had joined up. It looked lush and green last winter because of the mild weather, but it can get crushed if you walk on it too much, which is why I’ve laid a path of paving stones.”
Besides all the exotics, a few traditional favourites help boost the leafy effect. “I’ve used hostas and ivies around the patio to create a sense of leafy abundance. I’ve used hardy, native dryopteris ferns under the tree ferns and glossy-leaved evergreen shrubs such as aucuba and fatsia.”
Because this fabulous city garden is so sheltered, none of the plants needs to be protected from frost – apart from the young tree ferns. “I don’t take any risks if they have soft young shoots,” says Patrick, “so I wrap them in fleece. But otherwise I’m able to leave the tender plants to their own devices. Last winter two bird of paradise plants (strelizia) even survived.”
Patrick dreams of one day taking the tree ferns back to his native Ireland to create a garden there. “The warm, balmy climate would be perfect for them,” he says. In the meantime he’s keen to spread his enthusaism for jungle plants by sharing any spares with his neighbours. “There are echiums and a tree fern in the garden at number 9, a big cordyline in number 7 and a row of Paulownia tomentosa along the back of the gardens,” he says. “They help to create a screen that gives us all a bit of extra privacy.”
A nearby roundabout is now home to one of Patrick’s Canary Island date palms (Phoenix canariensis) and the road outside has a tropical twist too. “I planted a row of agapanthus along the street, where I saw the council about to put an area down to grass. They flowered for more than six weeks! Wherever I see a vacant spot of ground I wonder why people don’t do something interesting with it. It could be beautiful.” ___
THIS CHARACTERFUL COTTAGE is packed with green-fingered ideas. “I’m always experimenting,” says owner Louise Bateman. “No garden is ever finished, so whenever I have a new idea, I’ll go for it. If a plant doesn’t thrive or meet my expectations, I’ll try something else.”
Whether it’s building a wildlife pond, planting a stipa spiral or putting up some homemade fencing, Louise loves turning her artistic ideas into reality. Nowadays her garden is a picturesque retreat with bags of character and a billowing, natural look.
It’s a far cry from the scene that confronted Louise 11 years ago. “The house is a cedar bungalow built in the 1950s and had two previous owners, but neither of them was very passionate about plants. The garden wasn’t neglected as such, but there was about 30 years of plant growth to take in hand, and lots of conifers and overgrown trees and shrubs which took a team of professional tree surgeons a week to remove. We did the rest ourselves.”
Renovating the garden was far harder than Louise had anticipated. “We kept on finding concrete buried under the soil, which we’ve dug out and used to make the driveway wider. We prefer to recycle when we can – I’d rather not send anything to landfill if I can avoid it.”
Resourceful to the last, Louise is a devoted propagator of plants. “If I want a plant I tend to want a lot of it, as I like to plant things en masse for more impact. So, I’ll propagate new or interesting plants to make a fresh planting scheme. It takes time but I’m a great believer in growing plants from seed or cuttings whenever possible. It opens up the potential to plant on a grander scale and to experiment with plants without blowing your budget.”
Louise is a long time member of the Hardy Plant Society and the Royal Horticultural Society and takes part in their national seed distribution schemes, which helps her get hold of unusual plant varieties to grow from seed. “Some tender plants, such as my 13-year-old cannas are overwintered in my conservatory, and in the spring when I sow seeds every inch is packed with plants, so you can hardly get inside to water. There’s no space for any furniture and I dread cleaning it in June!”
Self-seeders are a good source of free plants, too. “I planted 100 allium bulbs in our front garden a few years back and now there’s about 1,000. Alliums grow so easily from seed. If you’ve got a plant that loves your soil, it makes sense to grow a lot of it.”
Louise also uses division to create more of the same plant. “A friend gave me a little piece of Carex comans and I divided it to plant individual clumps around the garden. Then, when they were big enough, I moved them to create edging for a path. I like their informal style and they’re evergreen too. I’ve paired the grasses with arctotis ‘Orange Prince’ – it’s the perfect colour to complement the carex’s dusty brown.”
The garden has a formal layout that belies Louise’s relaxed approach to self-seeders. “But within the formal structure I have plants spilling over border edges to create more interesting shapes.
“I decided to open my garden for the NGS one September,” she says, “and ended up introducing more late-summer flowering perennials such as dahlias, crinums, rudbeckias, kniphofia and heleniums – the perfect recipe for a hot border. They keep the borders bursting with colour right into the tail end of summer.”
Filling the garden with plants like this helps to keep weeds down. “I also avoid turning the soil. Digging gives annual weed seeds a chance to germinate,” she explains.
Louise has some secret allies when it comes to improving her loamy clay soil. “I have two ponies which keep me supplied with fertiliser and soil conditioner,” she says. “But instead of digging it in, I find that mulching with manure gets the garden off to a good start each year. But it has to be done before the soil dries out in spring because this is such a dry part of the country. The rain gets as far as Nottingham but then goes off up the river Trent and we don’t seem to get any of it!”
With little rainfall to rely on, Louise has wisely chosen plants that can cope with a bit of drought – silvery-leaved dianthus and artemisia keep her borders looking fresh. Soft-leaved Phlomis ruselliana has also proved a great architectural plant for sun or shade. “I’ve taken a leaf from Beth Chatto’s book, creator of the famous dry garden in Essex,” says Louise. “Her motto was ‘right plant, right place’. She’s absolutely right.”
