The Institute of Horticulture is the authoritative organisation representing all those professionally engaged in Horticulture in the UK & Ireland.

Its Membership comprises, and represents, all those involved in the Management, Growing and Marketing of all Edible and Decorative Horticultural Crops, and the Research, Education and Consultancy concerned with them. It also includes those concerned with Botanic Gardens and Landscaping, and the full range of Horticulture within Leisure Industries and those working in associated supply industries.

The Institute offers, not only recognition of status in the Horticultural Industry, but provides the opportunity to make a really effective contribution to the future of Horticulture, and its importance as a career.

The Institute's professional and technical meetings and other activities are arranged both at National and Regional level.

The Institute has eight Branches established throughout the United Kingdom and Ireland, and an increasing membership from overseas. Members are attached to the Branch where they live but are encouraged to attend meetings arranged in any other Branch area.
