Organised by RHS, the UK’s leading gardening charity, the Chelsea Flower Show has been held in the grounds of the Royal Hospital Chelsea in London since 1912. Described as the world's greatest flower show, it is a favourite of the British royal family. 

This year, many gardens include a focus on the future, tackling climate challenges through intelligence and innovation and embracing the wellbeing benefits of gardening through designing with fun and joy in mind. The 14 show gardens highlight a rich variety of garden purposes, including: gardens for respite; relaxation; connecting with friends; for children; communities and wildlife.  
 
For the first time RHS Chelsea Flower Show will feature a garden that harnesses the power of Artificial Intelligence (AI). The Avanade ‘Intelligent’ Garden, designed by RHS Chelsea Flower Show 2024 gold medal winning design team of Tom Massey and Je Ahn, includes a curated selection of climate-resilient plants and trees, which will be monitored by AI.

Practical garden elements of seating, water features and paving have been given a unique twist through the use of unusual materials, approaches and an abundance of traditional craftsmanship, including mycelium walls, semi-transparent enclosures, specialist tile makers and stone inscribing.

The Down’s Syndrome Scotland Garden, by Duncan Hall and Nick Burton (first time designers at RHS Chelsea), will include decorative tiles by contemporary artist and tile maker Francis Priest that surround a playful feature building. To highlight the misconceptions that people with Down’s Syndrome face this semi-wooded garden combines fun and mischievous features with both bold colourful planting and calming green colours to represent empathy and affection.

Helena Pettit, RHS Director of Shows and Gardens, said: “Our gardens, like people and plants have their own personalities. This year there is a huge diversity of inspiration and creativity reflecting the very different ways we want to use our gardens. Gardens to heal and restore, places to connect with others and entertain and gardens to play and have fun.

“So, whether you’re creating a place for relaxation, a haven for wildlife or simply want to revel in the joy of gardening, the 2025 RHS Chelsea Flower Show will be teeming with inspiration to help you bring more plants into your home.”

The London Square Chelsea Pensioners Garden, designed by Dave Green, is a place for the Chelsea Pensioners to share time with friends or family or to enjoy quiet reflection. The woodland space, filled with striking trees and a sheltered, central seating area will include vibrant planting to the garden boundaries to reflect the ceremonial life and stories of the Pensioners.
 
Many of the gardens have been inspired by natural landscapes and wild plant communities. Whether it is the coast of northeast Scotland, the self-seeding plant communities around volcanoes or the growing environment in Mallorca.

The Hospice UK: Garden of Compassion by Tom Hoblyn draws climate and planting parallels between County Durham and mountainous areas of the Mediterranean and The King’s Trust Garden: Seeding Success by Joe Perkins, set in a volcanic environment, highlighting how seeds represent the potential for life, growth and optimism for the future, drawing parallels with the potential for young people.
