The RHS Chelsea Flower Show 2026 episode 11 brought together its most memorable Friday evening of the week, with Monty Don and Arit Anderson hosting from a sunlit showground. Key themes: the Eden Project’s Bring Me Sunshine garden, bold summer colour trends, night-scented plants with Carol Klein, bat conservation garden, Adam Frost on garden structures, Cayley Sisters mushroom business, future-proof trees, climate-adaptive planting (cycads, Australian plants), RHS Director General Clare Matterson (gnomes, David Beckham, garden legacies), Dame Zandra Rhodes’ rooftop garden, Plant of the Year reveal (Hosta Red Ninja winner, two Hydrangea runners-up), and a closing Q&A.
The RHS Chelsea Flower Show 2026 episode 11 closes out the week with everything that makes Britain’s most celebrated horticultural event worth watching — bold colour, urgent science, extraordinary people, and one plant that stopped the judges in their tracks. As the heat finally arrived at the showground, hosts Monty Don and Arit Anderson led viewers through a Friday evening packed with design revelations, ecological urgency, and the kind of horticultural expertise that translates directly into better gardens at home. From Carol Klein uncovering the most fragrant plants for long summer evenings to Frances Tophill revealing the winner of the RHS Chelsea Plant of the Year, this episode brought the week to a memorable, sun-soaked close.
The showground itself felt different by Friday. Weeks of preparation, thousands of visitors, and days of judging had given everything a slightly looser, warmer atmosphere — and the planting looked better for it. Summer had arrived, and Chelsea’s designers were ready to show exactly what that meant.
Few gardens at the RHS Chelsea Flower Show 2026 carried as much purpose as the Eden Project’s Bring Me Sunshine garden, designed by Harry Holden and Alex McEllis. Inspired by the British seaside, the garden was built around a striking spider-like teaching structure — open, light, and deliberately communal. Rather than a conventional building, the designers created something that felt more like an invitation, a gathering space intended to draw young people in and teach them horticulture.
The garden used a newly developed paving and walling material called shell creek — local shells bound with limestone and a secondary binder — across its paths and surfaces. It carries a genuinely low carbon footprint, and the material itself represents exactly the kind of material innovation that Chelsea has championed in recent years. Most visitors walked past admiring the planting, barely noticing the ground beneath their feet contained something genuinely new.
Monty Don noted, from inside the garden looking out, that it revealed more to the eye than it did from the perimeter — a design characteristic that might count against it at Chelsea but would become a strength in its permanent home. After the show, the entire structure relocates to Morecambe, where the Eden Project is part of a major regeneration programme. The coastal planting palette — tough, salt-tolerant species capable of surviving a Morecambe January — was chosen with that northern seaside future explicitly in mind.

Bold Colour Dominates the Chelsea 2026 Planting Trends
All week at the RHS Chelsea Flower Show 2026, designer Jamie tracked the planting trends emerging across the showground. By Friday, his verdict was unambiguous: the dominant theme of 2026 was colour, uncompromising and unapologetic. More is more. Designers had largely abandoned restraint in favour of layered, joyful planting that threw away the rule book in the best possible way.
One garden exemplified this completely: an orange backdrop descending to green upcycled filing cabinets, then into sumptuous layers of geums, nasturtiums, geraniums, digitalis, and achillea. Pink, red, yellow, orange, and deep rose all colliding within the same border. No single colour dominated. Each one amplified the others. The effect was not chaotic — it was exhilarating.
However, nowhere at Chelsea was this approach executed more skillfully than in Arit Anderson’s Parkinson’s UK garden, which Jamie named his favourite planting of the entire show. Anderson used large colour blocks rather than individual specimen plants, massing perhaps twelve roses together to create a single dramatic impact. Dianthus, alliums, and poppies repeated at intervals through the border, creating what Jamie described as the glue that held the whole composition together. The result was colour used not just for beauty but for unity — an emotionally uplifting border that also demonstrated real structural intelligence. This year’s key take-home: more colour, everywhere.
Carol Klein Reveals the Best Night-Scented Plants for Summer Gardens
As the evenings lengthen and warm, the garden after dark becomes a different experience entirely. Carol Klein spent her Chelsea week exploring that shift — the way pale colours glow in moonlight, the way scent becomes more powerful once the sun goes down, and the way specific plants have evolved precisely to perform after dusk.
Her starting point was Jasminum polyanthum, which she described as the ultimate night-scented climber. Tender, and therefore needing protection, it can transport the senses entirely — a single breath of it and you might as well be in Tangier on a warm evening. For gardeners who need hardiness, Jasminum officinale provides a reliably winter-proof alternative that climbs freely over fences and walls.
Pittosporum tobira appeared next, valued for the scent of both its leaves and its flowers. Then came the Bat Conservation Trust’s nocturnal garden, designed by Melanie Hick, anchored by an enormous carved wooden bat sculpture. Here, Carol found white foxgloves — Digitalis purpurea alba — with their ghostly presence in the dark, and her favourite of all: Hesperis matronalis, known as sweet rocket, which holds back its perfume completely until dusk before releasing it fully into the evening air.
The botanical reason for this nocturnal timing is consistent across all these plants: they are pollinated by moths, and their long, narrow floral tubes evolved specifically to accommodate moth feeding. Understanding this mechanism changes how gardeners think about night planting. It is not simply aesthetic. These are ecological relationships shaped over millennia, playing out quietly in back gardens every summer night.
The Bat Conservation Trust Nocturnal Garden and Wildlife Planting
The Bat Conservation Trust garden at the RHS Chelsea Flower Show 2026 was remarkable as much for its mission as its planting. Designer Melanie Hick was explicit about her goal: creating a garden that supported all 18 UK bat species. Not one or two. All of them.
Britain’s bats are under serious pressure, with many species in genuine decline. The garden addressed this by demonstrating diverse planting — a rose, Francis E. Lester, alongside common foxgloves, plus hawthorn for flowers and berries, elderflower, and grasses with generous pollen loads — because different bat species have entirely different feeding habits. Some hunt moths. Some target beetles. To support the full range of British bats, a garden must attract the widest possible variety of insects. Food diversity for bats begins with plant diversity for gardeners.
The back wall of the garden contained a detail that most visitors would have missed: the timbers forming the wall structure had been pre-cut to the exact dimensions needed for bat boxes. After Chelsea, those ten bat boxes would travel to Cledak Community Gardens for local residents to construct and install. The garden won the People’s Choice Award at this year’s show — a fitting result for a space designed to serve not just the people walking past it, but the wildlife that would benefit from what those people take home.
Adam Frost on Using Garden Structures to Transform Your Space
All week at the RHS Chelsea Flower Show 2026, Adam Frost explored how the design ideas emerging from the showground could inspire practical upgrades at home. His Friday session focused on structures — pergolas, pavilions, garden buildings — and the thinking that makes them work.
Adam’s starting point was function before form. Before anything goes up, he argued, you need to ask what you actually want from the space. Somewhere to sit? Cook? Work? Play? That clarity drives everything else — the style, the materials, the positioning. The sun’s movement through the garden should determine where a structure sits, not habit or convenience.
One Chelsea garden placed its central structure not at the edge but in the middle of the space, which Adam described as brave and correct. The structure created privacy and outlook simultaneously. Crucially, it drove the design of the surrounding planting, with shapes radiating outward from it. Without planting wrapped around it, the structure would have felt dropped into the garden rather than grown from it. Instead, it anchored everything.
A second example showed the importance of sinking a structure into the landscape rather than imposing it at ground level — brought down by steps, it felt welcoming rather than overwhelming. A third garden used a non-uniform overhead structure that wound through the space, framing views and creating arches. Its colour scheme appeared both overhead and on the ground below, tying the entire garden together vertically and horizontally. The lesson was simple and powerful: structures should never be static afterthoughts. Done well, they become the bones the whole garden grows around.
The Cayley Sisters: A Mushroom Business Built Around Native UK Species
Inside the Great Pavilion at the RHS Chelsea Flower Show 2026, gold medals glinted throughout — but some of the most compelling stories came from the people behind the stands. Arit Anderson visited the Cayley Brothers exhibit, run not by brothers at all, but by two sisters who took their grandfather’s 1950s market garden name and brought it into the twenty-first century.
The Cayley sisters chose mushrooms as their specialism deliberately. Supermarkets offer almost nothing beyond the button mushroom, and the sisters identified that gap as an opportunity. They have since learned to grow native UK species that rarely appear in commercial cultivation — among them the coral tooth mushroom, a cousin of the popular lion’s mane, with an unusual crisp texture that suits people who dislike the softness of conventional mushrooms. Their approach is about far more than production. Each variety has its own personality, its own growth rhythm. They double in size every 24 hours. No two species look alike.
Their gold medal came from tireless work built around genuine passion. Both sisters have different strengths; both know the other’s weaknesses. They shifted their working hours around school drop-offs and childcare, one working early mornings, the other late at night. They described the horticulture industry as unexpectedly generous — open, lifting women in, giving confidence rather than withholding it. Their words about pride and confidence in what they do resonated across a week when Chelsea was full of people who had found their purpose through plants.
Climate Change Is Reshaping Which Trees Belong in British Gardens
One of the most urgent conversations at the RHS Chelsea Flower Show 2026 involved trees — specifically, the question of which trees will survive the British climate of 2050 and beyond. A nursery exhibiting inside the Great Pavilion had partnered with Kevin Martin, head of tree collections at the Royal Botanic Gardens, Kew, to bring scientific research directly into commercial horticulture.
The projections are striking. Studies suggest London could have the climate of Barcelona by 2050, and potentially something closer to Azerbaijan’s conditions by 2100. Of Britain’s native tree species — only 30 to 35 in total — many will struggle under those conditions. Pests, drought, and climatic extremes are already placing pressure on familiar species. Contrast that with the approximately 3,600 to 4,000 non-native cultivated tree varieties available, and the direction of travel becomes clear.
Kevin Martin’s framework was straightforward: select the right species for the right place for the right reason. Think beyond aesthetics — the bark, the leaf colour — and think about function: cooling, shade, rain interception, flood mitigation. Trees like Cercis canadensis Forest Pansy, with its purple leaf and suitability for dry urban environments, demonstrate that climate-resilient does not mean visually dull. Taxodium distichum, famous for surviving swampy conditions, becomes relevant as flood-prone areas increase. Sorbus alnifolia Olympic Flame brings spring flowers for pollinators, berries for birds, and architectural structure — all while carrying strong climate resilience credentials.
The trees planted today will spend a century in a world we cannot fully predict. Planting for beauty alone is no longer enough. Planting for function, resilience, and future conditions has become, as Martin put it, a cultural change — one that needs to start at Chelsea.
Monty Don Explores the Extraordinary Shift in What British Gardens Can Now Grow
Beyond trees, the RHS Chelsea Flower Show 2026 reflected something broader: climate change is fundamentally expanding the palette of plants that can thrive in British gardens. Monty Don explored this directly, contrasting what was possible forty years ago with what is increasingly ordinary now.
In the 1980s, a fig tree in a London garden carrying ripe fruit was exceptional. In 2026, Monty noted he harvests hundreds of figs from his own garden in August — sometimes July. Melianthus major, which once needed replacing every few years after frost killed it and flowered perhaps once every four years, now flowers reliably every season and overwinters outside without damage. These are not incremental shifts. They represent a meaningful change in what is possible.
At Chelsea, an entire garden planted exclusively with Australian species illustrated how far that shift could extend. Grass trees from the Australian outback — extraordinary architectural plants seen in the wild by Monty himself — will tolerate temperatures down to and slightly below freezing, provided drainage is exceptional.
Kangaroo paw needs poor soil, minimal nutrition, and perfect drainage; feed it or waterlog it and it dies quickly. Banksias evolved to survive extreme conditions. Tea tree hedges already grow and thrive in Cornwall. A cycad — a plant that predates the dinosaurs and evolved spines specifically to deter being eaten by them — was growing outside in the show’s London setting, viable as long as it has sharp drainage and stays dry in cold periods.
The conclusion was unavoidable: British gardens are going to change. The plants possible in them will change. The way they are grown will change. Chelsea 2026 was showing gardeners not just what is beautiful today, but what is coming.
The RHS Director General Reveals Gnomes, David Beckham, and What Happens to the Gardens
RHS Director General Clare Matterson joined the programme to reflect on what had been, by her own assessment, one of the best Chelsea shows in recent memory. Sold out before the gates opened. Sunshine on the final day. Gardens of genuine ambition. A Great Pavilion full of specialist growers with extraordinary depth of knowledge.
The return of garden gnomes to Chelsea — lifted from a ban that had stood for many years — emerged as the show’s unexpected talking point. Matterson described the decision to readmit gnomes as the most difficult she had made as Director General, delivered with a perfectly calibrated smile. Gnomes painted by Joanna Lumley and Sir Brian May had already generated publicity. Then came the moment: David Beckham had personally painted two gnomes for the RHS, both numbered seven, and both going to auction. Every penny from the sale supports the RHS school gardening campaign.
On the question of what happens to the gardens after the show, Matterson was emphatic: nothing goes to landfill. The Eden Project’s Bring Me Sunshine garden heads to Morecambe. The Trussell Trust food bank garden goes to a food bank in Northern Ireland. The RHS’s own Curious Garden will be used as a teaching resource at a further education college in Farnborough. Chelsea is the first stop. Every garden then finds its forever home.
Two new RHS shows — one at Sandringham, one at Badminton, both in July — were announced, extending the organisation’s reach into some of Britain’s most celebrated historic settings.
Dame Zandra Rhodes and the Sky Garden Above Bermondsey
Away from the Chelsea showground, one of the week’s most intimate moments came from a visit to fashion designer Dame Zandra Rhodes at her penthouse home within walking distance of the Shard. Her rooftop terrace — a garden in the sky above Bermondsey — is one of the most extraordinary private growing spaces in London.
The terrace has three distinct areas, each with its own character. The northern end is the camellia terrace, where eleven camellia trees grow in pots, the oldest a white-flowered specimen gifted to Zandra by Karl Lagerfeld fifty years ago and still blooming every spring. She divides her hostas every two years and gives plants away; she waters them with garlic water and lines pots with eggshells to deter slugs.
The middle section is Hydrangea Walk, where a wall painted Frida Kahlo blue provides the backdrop for white hydrangeas that fill the space in high summer. Herbs — sage, thyme, mint kept separate to contain its rhizome spread — grow alongside three tomato plants. The south side carries plants that have been with Zandra since 1972, including a euphorbia that once belonged to artist Andrew Logan and had to be craned up to the terrace when she first moved in.
Objects from her extraordinary life fill the space alongside the plants: a Mexican statue from a party at Aspinall’s decades ago, a fiberglass shield from her set design for The Magic Flute in San Diego. She talks to plants that are struggling. She comes to Chelsea each year specifically to compare how her plants perform against the showground’s best specimens, and to look for something she might just be able to squeeze into one more pot. This year, she was considering mad grasses.
Hosta Red Ninja Wins the RHS Chelsea Plant of the Year 2026
The RHS Chelsea Plant of the Year is among the most coveted titles in horticulture. Breeders travel from across the world with their finest specimens. Judges evaluate novelty, garden performance, and genuine appeal to ordinary gardeners. This year’s shortlist came down to three plants — and the winner was extraordinary.
In third place: Hydrangea Velvet Night Red Lace. A deeply unusual hydrangea, its bold dark colour scheme was firmly on trend for 2026’s gardens. It needs moisture and mulching, tolerates partial shade, but should avoid full midday sun, which can scorch the leaves. Position it at the edge of dappled tree shade and its rich purple colouring activates fully.
In second place: Hydrangea Paniculata Groundbreaker Ruby — described as a genuinely versatile plant that works in modern, cottage, and mixed gardens alike. Its most significant claim to novelty was being the first paniculata hydrangea to function as true ground cover, reaching no more than 40cm tall and 70cm wide. Its flowers open in white-green, transition to pink through summer, then deepen to ruby by autumn and hold that colour through winter. Year-round colour from a single plant. Monty could immediately see why it had made the shortlist.
The winner — Hosta Red Ninja — was something genuinely new. Bred in Denmark, it emerged with a stable red colouration unlike anything previously seen in hostas: deep red stems, red veining on the leaves, and a painterly variegation that shifts dramatically depending on light conditions. In shade, it takes on a mottled, beetroot-green quality. In full sunshine, it fires up into a genuinely vivid red. The plant’s versatility extends to its cultivation: it can be grown in a pot and moved to the light level it needs in any given moment, making it unusually flexible for small spaces. Both finalists for the RHS Chelsea Plant of the Year 2026 had come remarkably close.
Frances Tophill and Monty Don reviewed all three together, with honest opinions. Monty admitted hostas were not his usual territory — slugs are the perennial issue in his garden — but acknowledged that gardeners looking for colour in partial shade would find the Red Ninja genuinely compelling. The judges had seen something in it that went beyond trend. Novelty, performance, and real-world appeal: Hosta Red Ninja had all three.
For the summer ahead, Arit Anderson’s final advice was to plant tender annuals for maximum container colour — zinnias, cosmos, nasturtiums, and tithonias among her top choices. Monty tackled the perennial problem of a failing lemon tree: frost damage most likely, the solution being to cut back to living growth and keep the plant cool, humid, and dry at the base through winter — avoiding the common mistake of keeping it too warm indoors. On green water features, he was practical: algae feed on fertility washing into water from surrounding soil, so stone edging that keeps nutrient levels low is far more effective than chemical treatments.
Chelsea 2026 ended as it had spent the week — generous with ideas, rigorous in its horticulture, and genuinely enthusiastic about getting Britain’s gardeners outside and growing.
FAQ RHS Chelsea Flower Show 2026 episode 11
Q: What plant won the RHS Chelsea Plant of the Year 2026?
A: Hosta Red Ninja won the RHS Chelsea Plant of the Year 2026. Bred in Denmark, it features deep red stems, red-veined leaves, and striking painterly variegation. Its colour intensity shifts with light levels — mottled beetroot-green in shade, vivid red in full sun. Growing it in a pot allows gardeners to move it to the ideal light position as needed.
Q: What were the runners-up for the RHS Chelsea Plant of the Year 2026?
A: Second place went to Hydrangea Paniculata Groundbreaker Ruby, the first paniculata hydrangea to function as true ground cover, reaching just 40cm tall. Its flowers transition from white-green to pink, then deepen to ruby and hold that colour through winter. Third place was Hydrangea Velvet Night Red Lace, a bold dark-coloured variety suited to partial shade and modern garden planting schemes.
Q: What are the best night-scented plants for a summer garden?
A: Jasminum polyanthum is considered the ultimate night-scented climber, though it is tender and needs protection. For a hardy alternative, Jasminum officinale climbs fences and walls reliably. Pittosporum tobira offers scented leaves and flowers. Hesperis matronalis (sweet rocket) releases its strongest perfume only after dusk. White foxgloves (Digitalis purpurea alba) add a ghostly visual presence in evening light. Most night-scented plants have long, tubular flowers because moths pollinate them.
Q: How do you stop a water feature from turning green?
A: Algae grow when excess nutrients wash into the water, typically from surrounding compost or soil carried in by rain. The most effective prevention is edging water features with stone or gravel rather than planted borders, which keeps fertility levels low. Reducing the nutrient load in the water removes the algae’s food source and gives the clearest long-term results without chemical treatments.
Q: Why are British native trees struggling to cope with climate change?
A: Britain has only 30 to 35 native tree species, many of which are already under pressure from pests, disease, and climatic extremes. Research suggests London could have Barcelona’s climate by 2050 and conditions closer to Azerbaijan’s by 2100. Many native species simply will not be resilient enough for those conditions. Horticultural experts are increasingly recommending climate-adapted non-natives from a cultivated palette of 3,600 to 4,000 varieties.
Q: What annuals are best for maximum colour in pots this summer?
A: Zinnias, cosmos, nasturtiums, and tithonias are all excellent choices for high-impact summer container colour. These tender annuals grow quickly and produce prolific blooms across a long season. Growing them in pots allows easy repositioning to maximise light, and they can be combined freely for layered, bold effects. Starting them from seed is straightforward, and they perform well even for less experienced gardeners.
Q: How do you revive a lemon tree that has died back?
A: Dieback on a lemon tree is almost always caused by frost exposure or being kept too warm and dry indoors. Cut back all dead growth to living wood — dead stems will never regenerate. Once trimmed to healthy tissue, the plant will reshoot. Long-term, lemon trees need cool, humid conditions in winter with dry roots, and in summer should be watered no more than once a week to thrive.
Q: What Australian plants can now be grown in British gardens?
A: Several Australian species are increasingly viable in British conditions as temperatures rise. Grass trees tolerate light frost provided drainage is sharp. Kangaroo paw thrives in poor soil with excellent drainage — feeding it or waterlogging it quickly causes failure. Banksias evolved for extreme conditions and adapt well. Tea tree hedges already grow successfully in Cornwall. All these plants share a critical requirement: outstanding drainage and low-fertility soil.
Q: How do you create a garden that attracts bats?
A: Planting diversity is the single most important factor. Different bat species hunt different insects, so a range of flower shapes — open roses, tubular foxgloves, flat-headed umbellifers — attracts the widest insect variety. Water is essential, drawing insects at low flight levels. Hawthorn, elderflower, and pollen-rich grasses support multiple bat species. Installing bat boxes provides roosting habitat. Britain has 18 bat species, many in decline, and even modest garden changes can make a measurable difference.
Q: What should you consider before adding a structure to your garden?
A: Start with function: decide whether the space is for sitting, cooking, working, or play, then choose a style — modern or traditional — to suit. Position is driven by how the sun moves through the garden, not convenience. Any structure placed in the middle of a garden needs planting radiating from it, otherwise it looks dropped in rather than designed. Repeating structural colours and materials in the surrounding planting and containers ties the whole garden together effectively.
