Learn about the RHS Plant Committees and the work they do to support us in our mission to inspire everyone to grow
The seven RHS Plant Committees provide an invaluable source of horticultural expertise. Committee members come from all corners of horticulture – amateur, professional and commercial – and voluntarily commit their time to act as our ambassadors, helping us to promote plant excellence, extend our regional, national and international networks, and sharing their passion for plants.

RHS Plant Committee Annual Awards
The RHS Plant Committee Annual Awards were created to recognise those who are making an outstanding contribution within their plant group.
Meet the RHS Plant Committees
The Bulb Committee evolved in 2013 from the Daffodil and Tulip Committee (formed 1884) and its wider remit now covers bulbs and other subterranean plants across all seasons, including corms, tubers and rhizomes. Its members also contribute to the production of the Daffodil, Snowdrop and Tulip Yearbook and help to organise and judge relevant plants at regional horticultural shows and competitions. The committee has strong links internationally, particularly in Holland, and representatives of the RHS Lily Group also sit on this committee. The RHS is the International Cultivar Registration Authority for daffodils and lilies.
Fruit, Vegetable and Herb Committee
The Fruit, Vegetable and Herb Committee was formed in 1858 and is the oldest Plant Committee. Its members also assist with the scheduling and judging of fruit, vegetable and herb classes at horticultural competitions and shows, and participate in cultivar identification at various locations around the country. They contribute expertise to RHS applications and campaigns, and membership includes representatives from the RHS Fruit Group.
Herbaceous Plant Committee
The Herbaceous Plant Committee, formed in 1859 as the Floral Committee and renamed in 2005, has a huge remit covering hardy herbaceous perennials such as chrysanthemums, carnations and pinks, delphiniums and grasses. It works collaboratively with the Tender Ornamental Plant Committee on the assessment of seasonal bedding plants, both in formal trials and within the rolling review of AGMs. The RHS is the International Cultivar Registration Authority for delphiniums, dahlias and Dianthus.
Joint Rock Garden Plant Committee
The Joint Rock Garden Plant Committee was formed in 1936 and comprises an equal numbers of experts representing the RHS, Alpine Garden Society and the Scottish Rock Garden Club. As well as its own meetings, the committee attends shows and events all over the UK, judging and assessing a wide range of rock garden and alpine plants for RHS Plant Awards, including the AGM.
The Orchid Committee was formed in 1889 and holds meetings around the country, working with local orchid societies and assessing more than 200 plants for RHS Plant Awards every year. The committee has strong international links, and its members represent the committee and the RHS at events all over the world. The committee assists in the planning and delivery of the annual RHS Orchid Show and The Orchid Review Yearbook publication. The RHS is also the International Cultivar Registration Authority for orchid hybrids.

Woody Plant Committee
The Woody Plant Committee was formed in 1859 as part of the Floral Committee and renamed in 2005. It is the source of expertise for hardy trees and shrubs, which includes old hybrid and species roses as well as hardy climbing plants. The committee makes study visits to many gardens with important collections. It has strong links with the International Dendrology Society and other relevant societies, and membership includes representatives from the RHS Rhododendron, Camellia and Magnolia Group.
