RHS CHELSEA FLOWER SHOW 2024
The Octavia Hill Garden By Blue Diamond with the National Trust
Ann-Marie Powell Gardens are thrilled to be returning to the RHS Chelsea Flower Show in 2024 – Show times 21st – 25th May!
Working with our sponsors Blue Diamond Garden Centres and the National Trust our Main Avenue Show Garden celebrates Octavia Hill (1838-1912), the pioneering co-founder of the National Trust, who believed green spaces and gardens were vital in everyone’s life.
Our urban community wildlife garden responds to the idea that if Octavia Hill were alive today, she would still be working to give urban communities access to nature. Research continues to show the importance of green space for both physical and mental health. While celebrating Hill’s legacy, our garden also aims to inspire innovative gardens that connect people with the beauty and complexity of the natural world.
Our design approach is a showcase for sustainability and climate change resilience, with peat-free plants, reclaimed materials and low-carbon build techniques. We want to show that urban brownfield sites can be reclaimed to create beautiful, biodiverse spaces with huge wellbeing benefits.
We will be sharing more about the garden as we get closer to the show, but for now, we are delighted to share some background information and our visuals.

Our Inspiration: Octavia Hill
The inspiration for the garden starts and ends with pioneering social reformer Octavia Hill (1838-1912). We have to thank Blue Diamond for their inspiring idea to celebrate Hill’s life and achievements at Chelsea 2024 and the wonderful journey of discovery this has taken us on.
Octavia Hill was one of the founders of the National Trust. She believed that ‘the healthy gift of air and the joy of plants and flowers’ were vital in everyone’s life. Hill worked tirelessly to improve urban housing and protect green space. Yet today, Hill is little known, and one-in-three people in Britain still don’t have access to nearby nature-rich spaces. We want to change that.
Our garden is imagined to be located on an urban brownfield site. This beautiful, gardened, plant-filled urban community wildlife garden is designed to stimulate physical, mental, and social well-being. The garden increases urban-biodiversity and encourages visitors to feel that they are part of nature by making intimate connections with plants and wildlife.
The garden is built as a series of open-air sitting rooms, where visitors can experience different views and atmospheres. Sloping level changes with wheelchair accessible paths, lead visitors to a planted shade canopy, observation platform, wildlife pond or walking stream as the mood takes them, providing multiple opportunities to enjoy the garden wildlife, feasting on the pollinator-friendly planting.


Our Beliefs
Octavia Hill believed everyone needs access to green space and ‘outdoor sitting rooms’ (gardens). The National Trust, Blue Diamond, Ann-Marie Powell Gardens and the RHS all share this belief, which is even more relevant to society today. Our garden embraces this idea by envisioning how Octavia Hill would work to give urban communities access to nature if she were alive in our present day. If you are living in a neighbourhood built after the millennium, your local park is more likely to be smaller and you are more likely to have to travel further to reach it than pre-2000. Statistical analysis suggests the decline in new green space provision after 2000 can now be associated with at least nine million fewer trips to green space a year.
The National Trust, Blue Diamond and Ann-Marie Powell Gardens believe in gardens for all. For people, nature and wildlife – just as Octavia Hill did. Gardens have the power to transform lives. Here at AMPG, we feel that we have a social responsibility to promote gardening and to inspire the creation of as many gardens as possible. Our urban parks, verges and gardens can increase plant diversity, connect us with nature and nurture wildlife. Our urban community wildlife garden, set on a brownfield site, shows plants and wildlife can thrive in places you may not expect.
Sustainability
Our garden includes many plants chosen to provide food sources for a range of wildlife, including pollinators, all year round. A 2021 study by scientists at London’s Natural History Museum revealed that the UK is one of the worst-rated nations in the world in retaining our natural animals and plants, whilst the 2021 Bugs Matter findings showed UK’s insect numbers have reduced by a staggering 59% between 2004 and 2021.
We believe that biodiversity isn’t a luxury, or a ‘nice to have’. When it is diminished, we all lose out.
We also believe that great things can be achieved whilst working to the highest environmental standards – using reclaimed materials, peat-free plants, environmentally sensitive hard landscaping and resilient plants.
After the show, the garden will be given a second life at Blue Diamond owned Bridgemere Show Gardens where it will be open to the public to enjoy all year round.
Gardens can and should be for everyone.
