The RHS Chelsea Flower Show returns to the Royal Hospital Chelsea from 19 to 23 May 2026, transforming a corner of West London into the world’s most celebrated horticultural showcase. But the Chelsea name in May means more than just the main show — two extraordinary free festivals, Chelsea in Bloom (18-24 May) and Belgravia in Bloom (18-24 May), turn the surrounding streets into an open-air gallery of floral artistry. If you love flowers, London in late May is simply unmissable.
At Olive Tree Florist, we have been crafting bespoke floral arrangements across London for years, and the Chelsea season is our favourite time of year. Here is everything you need to know about the 2026 Chelsea flower festivals — from the headline trends to the installations you cannot miss, and how to bring that inspiration into your own home.
What Is the Chelsea Flower Show?
The RHS Chelsea Flower Show, organised by the Royal Horticultural Society, has been the gold standard of garden design since 1913. Held on the grounds of the Royal Hospital Chelsea, it attracts over 150,000 visitors each year, including members of the Royal Family, celebrities, and the world’s finest garden designers.
The 2026 edition promises cutting-edge garden design, spectacular floral displays, and the best shopping for plant enthusiasts. The show gardens are the main attraction — ambitious, immersive installations that push the boundaries of what garden design can achieve.
Ticket alert: Chelsea Flower Show tickets sell out quickly. RHS members get priority booking and discounted entry. If you haven’t secured yours yet, check availability at rhs.org.uk/chelsea.
Chelsea in Bloom 2026: Zodiac-Inspired Florals
For those who cannot swing a ticket to the main show — or simply cannot get enough of spring florals — Chelsea in Bloom is the answer. This free festival runs 18-24 May 2026 and sees the boutiques, restaurants, and shopfronts of Chelsea transformed with extravagant floral installations.
This year’s theme brings a celestial twist: zodiac-inspired florals with a special tribute featuring David Attenborough installations. Expect to see Aries rendered in fiery red blooms, Taurus in earthy greens and sculptural succulents, and Pisces flowing with cascading blue delphiniums and irises. The competition between retailers grows fiercer each year, with participants vying for the coveted “Best Floral Display” award.

Belgravia in Bloom 2026: Fairy Tales Come to Life
Running concurrently from 18-24 May, Belgravia in Bloom adopts the enchanting theme “Fairy Tales of Belgravia”. Expect Elizabeth Street, Motcomb Street, and Pimlico Road to be transformed with installations inspired by classic fairy tales — think enchanted rose displays, magical woodland scenes, and floral interpretations of beloved storybook characters.
Belgravia in Bloom has become a firm fixture in London’s cultural calendar, drawing families, photographers, and flower enthusiasts from across the capital. The installations remain in place for a full week, giving you ample opportunity to explore at your leisure.

2026 Floral Trends from Chelsea
Chelsea sets the agenda for floral design globally, and 2026 is no exception. Here is what the show tells us about the direction of flowers this year.
Intentional Simplicity
The defining characteristic of this year’s designs is intentional simplicity. Rather than traditional mixed arrangements with a little bit of everything, florists are embracing the power of repetition and restraint — using a single species of flower, or a carefully limited palette, to create visual impact through cohesion rather than variety.
This trend translates beautifully to the home. A dozen identical peonies in a simple glass vase makes a stronger statement than a busy mixed bouquet. At Olive Tree Florist, our mono-floral arrangements showcase the beauty of individual stems — from elegant white tulips to dramatic deep-red roses.
Organic Movement and Tactile Contrast
Luxury London florists note that 2026 designs “feel alive, organic yet intentional.” Florists are layering textures — dried grasses meeting velvety petals, feathery ferns framing crisp anthuriums. Loose, asymmetrical shapes replace rigid, formal arrangements, reflecting a broader cultural shift towards authenticity and natural beauty.
Sustainability and British-Grown Flowers
Sustainability continues to dominate the conversation. British flower farms are thriving, and Chelsea increasingly showcases home-grown blooms. The carbon footprint of imported flowers — particularly those air-freighted from Kenya, Ecuador, and the Netherlands — is under scrutiny.
At Olive Tree Florist, we prioritise seasonal, British-grown flowers wherever possible. Our subscription service features the best of what is blooming locally each month, reducing food miles and supporting UK growers.

How to Bring Chelsea Style Home
You do not need a show garden budget to channel Chelsea style. Here are our florist’s tips for creating show-worthy arrangements at home.
1. Choose Seasonal British Blooms
May is one of the most abundant months for British flowers. Look for peonies (the undisputed star of late spring), ranunculus with their layers of tissue-paper petals, tulips still going strong in early May, fragrant and fleeting lilac, delicate sweet peas, and lily of the valley with its tiny bells of pure fragrance.

2. Embrace the Single-Variety Look
Following the intentional simplicity trend, try arranging a single variety in a statement vase. Twelve stems of the same flower, cut to the same height, creates an elegant, contemporary look that photographs beautifully.
3. Add Dried Elements
Incorporate dried grasses, seed heads, or preserved foliage to add textural contrast. Bunny tails, pampas grass, and dried eucalyptus pair wonderfully with fresh blooms and extend the life of your arrangement.
4. Think Beyond the Vase
Chelsea designers are using vessels in unexpected ways — vintage teapots, terracotta pots, even repurposed industrial containers. A beautiful arrangement deserves a beautiful home.
