The RHS Grow App is a digital gardening companion developed by the Royal Horticultural Society (RHS), the world's leading gardening charity based in the United Kingdom. Designed to provide personalized expert advice, plant identification tools, and seasonal gardening tips, the app serves as a modern extension of the RHS mission to inspire and inform gardeners of all skill levels. The technology is developed and maintained primarily within the UK.

As a non-profit initiative, the app reflects over two centuries of horticultural excellence. The Royal Horticultural Society was founded in 1804 and remains the ultimate owner and operator of the service. By utilizing its vast database of plant knowledge, the RHS ensures that the app provides scientifically backed guidance for both indoor and outdoor gardening, helping to promote biodiversity and sustainable gardening practices globally.
