About Royal Horticultural Society (RHS)

Geographic reach: United Kingdom, Europe, Global exhibitors and visitors

The Royal Horticultural Society (RHS) is the United Kingdom’s leading gardening charity and one of the world’s most influential horticultural organisations, dedicated to improving the science, art and practice of horticulture and helping people and plants to grow. Founded in the early 19th century, the RHS has evolved from a learned society into a modern charity that combines world‑class flower shows, landmark gardens, research, education and community programmes.

Its purpose is to nurture a healthier, happier world through gardening, supporting both amateur and professional audiences. The RHS is best known globally for organising flagship flower shows including RHS Chelsea Flower Show, Hampton Court Palace Garden Festival and RHS Flower Show Tatton Park, which showcase cutting‑edge garden design, horticultural excellence and a broad exhibitor base from growers, landscapers and garden product suppliers to lifestyle and hospitality brands.

These events attract visitors and exhibitors from across the UK and overseas, offering high‑impact brand visibility, product launch platforms and curated specialist audiences focused on gardening, outdoor living and design. Beyond events, the RHS operates major visitor gardens, runs gardening science and collections at RHS Hilltop – the UK’s first dedicated research centre for gardening science – and invests in education, school gardening and community greening initiatives.

It also publishes books, podcasts and digital content, including the RHS Grow app, extending its reach to millions of gardeners and trade stakeholders worldwide. For exhibitors, partnering with the RHS provides access to trusted horticultural credentials, strong media coverage, and an engaged membership base seeking innovative products, services and experiences related to plants, design, construction, outdoor structures, hospitality and garden lifestyle.
