Gardening events in Oxfordshire and beyond worth a visit
Few pursuits combine beauty, creativity and craftsmanship quite like gardening. Across Oxfordshire and the surrounding counties, the horticultural calendar offers opportunities to step inside some of Britain’s finest gardens, discover unusual plants and hear from the experts shaping the future of garden design.
From world-famous flower shows in London to charming village open gardens and specialist plant fairs on Oxfordshire’s doorstep, these events provide inspiration for seasoned gardeners and newcomers alike. Whether you’re planning a complete redesign of your outdoor space or simply looking for an enjoyable day out surrounded by colour and fragrance, these are some of the gardening events worth seeking out in 2026.
RHS Malvern Spring Festival
Three Counties Showground, Worcestershire. 07 to 10 May 2026
The arrival of the RHS Malvern Spring Festival signals the beginning of the gardening season in earnest. Set against the backdrop of the Malvern Hills, the event combines spectacular show gardens, floral displays and specialist nurseries with a relaxed atmosphere that feels distinctly different from some of the larger RHS shows.
Visitors can expect everything from cutting-edge garden design and sustainability-focused planting schemes to practical advice for everyday gardeners. The Festival of Houseplants has become a particular draw in recent years, reflecting the continuing popularity of indoor gardening, while talks, demonstrations and workshops provide plenty of opportunities to pick up new ideas before summer gets underway.
RHS Chelsea Flower Show
Royal Hospital Chelsea, London. 19 to 23 May 2026.
No event carries greater prestige in the gardening world than RHS Chelsea Flower Show. For more than a century, Chelsea has been where the latest horticultural trends are unveiled, where designers push the boundaries of creativity and where growers showcase plants at the absolute peak of perfection.
Beyond the headline show gardens, Chelsea offers countless moments of inspiration. The Great Pavilion is a destination in its own right, filled with award-winning growers displaying extraordinary blooms, rare specimens and innovative planting combinations. Even for visitors without a large garden, the event provides a glimpse into the artistry and imagination that make British gardening admired around the world.
Chinnor Open Gardens
Chinnor, Oxfordshire. 06 & 07 June 2026.
While the major flower shows attract international attention, events such as Chinnor Open Gardens celebrate something equally important: the passion and creativity of everyday gardeners. Across the village, private gardens open their gates to visitors, revealing spaces that are rarely seen by anyone beyond family and friends.
Part of the appeal lies in the variety. Visitors can wander from traditional cottage gardens overflowing with roses and herbaceous borders to productive allotments, wildlife-friendly plots and more contemporary landscapes. The event also offers a sense of community that larger shows cannot replicate, with plant stalls, homemade refreshments and local fundraising creating a welcoming atmosphere throughout the weekend.
Rare Plant Fair at Waterperry Gardens
Waterperry Gardens, Oxfordshire. 07 June 2026.
For gardeners who enjoy seeking out something unusual, the Rare Plant Fair at Waterperry Gardens is one of the highlights of the Oxfordshire horticultural calendar. Specialist nurseries travel from across the country to showcase plants that are unlikely to be found in conventional garden centres, from rare perennials and heritage varieties to unusual shrubs and trees.
The setting adds considerably to the appeal. Waterperry’s beautifully maintained gardens provide inspiration at every turn, allowing visitors to see mature planting schemes while discovering new additions for their own gardens. Conversations with knowledgeable growers often prove just as valuable as the plants themselves, making the event a favourite among serious enthusiasts.
Blenheim Palace Flower Show
Blenheim Palace, Woodstock. 19 to 21 June 2026
There are few more dramatic settings for a flower show than the grounds of Blenheim Palace. Surrounded by one of Britain’s most impressive country estates, the event combines horticultural displays with lifestyle exhibits, artisan producers and garden retailers, creating a broad appeal that extends well beyond dedicated gardeners.
The show’s scale means visitors can spend an entire day exploring. Specialist growers sit alongside garden furniture suppliers, designers and craftspeople, while floral displays provide plenty of inspiration for the season ahead. With the palace and parkland forming a spectacular backdrop, it is as much a summer day out as it is a gardening event.
RHS Badminton Flower Show
Badminton Estate, Gloucestershire. 08 to 12 July 2026
One of the most anticipated additions to the gardening calendar, the inaugural RHS Badminton Flower Show arrives in 2026 at the historic Badminton Estate. The new event represents an exciting chapter for the RHS and offers visitors the chance to experience a major flower show in a fresh setting renowned for its landscape and heritage.
Visitors can expect the hallmarks of a flagship RHS event: imaginative show gardens, exceptional plant displays, leading horticultural experts and a strong emphasis on gardening innovation. Its location also makes it particularly attractive for visitors from Oxfordshire, providing a world-class flower show experience within easy reach of home.
RHS Sandringham Flower Show
Sandringham Estate, Norfolk. 22 to 26 July 2026
Another newcomer to the RHS portfolio, the Sandringham Flower Show combines royal surroundings with horticultural excellence. Hosted at the King’s country estate, the event promises a unique blend of gardening inspiration and access to one of Britain’s most celebrated landscapes.
As with other RHS events, visitors can expect show gardens, specialist nurseries and expert-led demonstrations. Yet the setting itself is likely to be one of the major attractions, offering an opportunity to explore a historic estate while enjoying the latest developments in garden design and planting.
Rare Plant Fair at Adwell House
Near Thame, Oxfordshire. 06 September 2026
As summer begins to fade, the Rare Plant Fair at Adwell House provides gardeners with one final opportunity to add something special to their borders before autumn planting gets underway. The fair has built a loyal following thanks to its focus on specialist growers and high-quality plants.
Adwell House itself is something of a hidden gem. The historic house and gardens create a wonderfully intimate setting for the event, allowing visitors to browse at a leisurely pace while gathering ideas for the seasons ahead. For many gardeners, it represents the perfect conclusion to the year’s horticultural calendar.
More than just plant shopping
The enduring popularity of gardening events reflects a simple truth: gardens are best experienced in person. Seeing planting combinations at their peak, speaking directly with growers and discovering new ideas in real-world settings offers a level of inspiration that books and social media rarely achieve.
Whether you’re drawn to the grandeur of Chelsea, the specialist expertise of a rare plant fair or the charm of a village open garden, these events celebrate the creativity, knowledge and enthusiasm that continue to make gardening one of Britain’s most beloved pastimes.
