The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity.

The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. As of 2023 the president was Keith Weed and the director general was Clare Matterson CBE.

RHS Garden Wisley is a garden run by the Royal Horticultural Society in Wisley, Surrey, southwest of London. It is one of five gardens run by the society, the others being Harlow Carr, Hyde Hall, Rosemoor, and Bridgewater (which opened on 18 May 2021). Wisley is the second most visited paid entry garden in the United Kingdom after the Royal Botanic Gardens, Kew, with 1,104,362 visitors in 2024. The gardens are Grade II* listed.

RHS Garden Hyde Hall is a public display garden run by the Royal Horticultural Society in the English county of Essex. It is one of five public gardens run by the society, alongside Wisley in Surrey, Harlow Carr in North Yorkshire, Rosemoor in Devon, and Bridgewater in Greater Manchester.

The 360-acre Hyde Hall site encompasses a range of garden styles, from the Dry Garden with drought resistant plants, to the Hilltop Garden with roses and herbaceous borders. Hyde Hall has had a lot of investment in recent years with the opening of a new Global Growth Vegetable Garden (in 2017) showing vegetables from around the world, a new Winter Garden (in 2018) hosting an RHS Trial of Cornus, a new Welcome building (in 2017), and Hilltop Complex (in 2018) featuring a new restaurant and activity centre.
