The RHS Science Circle brings together people who are passionate about horticultural science, plant research and conservation. Their support helps advance pioneering work at RHS Hilltop – The Home of Gardening Science, the UK’s first dedicated centre for horticultural science, conservation and learning, where more than 130 scientists, specialists and students are creating the knowledge and solutions needed for the future of gardening. This work helps provide trusted, evidence-based advice that can benefit up to 41 million gardeners across the UK.
