Plant Heritage

Plant Heritage is a British conservation charity dedicated to the preservation, documentation, and sustainable use of cultivated plants and garden varieties. It operates through a national network of regional branches, volunteer-led nurseries, and accredited collections to safeguard horticultural diversity across the United Kingdom. The organisation engages with institutions, collectors, botanical gardens, nurseries, and heritage sites to record threatened cultivars, promote best-practice conservation, and raise public awareness of plant variety loss.

History

Plant Heritage was founded in 1978 amid growing concern about the disappearance of historic and locally important garden plants across the United Kingdom. Early supporters and figures associated with the organisation included horticulturists and curators active at institutions such as the Royal Horticultural Society, the Royal Botanic Gardens, Kew, and the National Trust. During the 1980s and 1990s the charity expanded its network, formalising the National Plant Collection scheme and developing ties with universities, such as the University of Oxford and the University of Cambridge, which had academic interests in taxonomy and plant genetics. Plant Heritage engaged with policy debates at national levels involving bodies like the Department for Environment, Food and Rural Affairs and participated in international dialogues alongside organisations such as Botanic Gardens Conservation International and the International Union for Conservation of Nature. Over subsequent decades the charity adapted to changing horticultural practice, collaborating with museums, archives, and societies including the Garden History Society and the Royal Society of Arts to contextualise cultivar provenance and cultural heritage.

Mission and Activities

Plant Heritage’s mission focuses on conserving cultivated plants by documenting diversity, maintaining living collections, and encouraging propagation of threatened varieties. The charity’s activities include the accreditation of National Plant Collections, the collation of cultivar databases, and the provision of conservation guidelines informed by practice at institutions like the Eden Project and Wakehurst Place. Plant Heritage organises events, conferences and symposia that draw speakers from organisations such as the Linnean Society, the National Trust, and the Royal Botanic Garden Edinburgh. The organisation also issues technical advice to partner gardens and historic houses like Kew Gardens, RHS Wisley, and many independent garden owners, while liaising with regulatory and advisory bodies including Historic England and the Heritage Lottery Fund. Plant Heritage publishes guidance and newsletters for members and liaises with trade and professional groups such as the Horticultural Trades Association and the Chartered Institute of Horticulture.

Collections and Conservation

Central to Plant Heritage is the National Plant Collection scheme, which encourages individuals and institutions to hold, document and make available collections of cultivars of particular genera or groups. Accredited collections are maintained by collectors, botanical gardens, arboreta and nurseries, ranging from specialist holdings at places like Sheffield Botanical Gardens and Cambridge University Botanic Garden to private collections associated with estates and trusts. Documentation standards reference taxonomic resources and herbarium practice at institutions such as the Natural History Museum and the Royal Botanic Gardens, Kew. Conservation practice combines field-maintenance, propagation by cuttings or grafting, seed banking collaborations with organisations such as the Millennium Seed Bank and ex situ conservation strategies used by botanic gardens internationally. Plant Heritage monitors threats to cultivated diversity including loss of heirloom fruit and vegetable cultivars, the decline of historic rose and apple varieties important to trusts like the National Trust, and the impacts of pests and diseases observed at sites such as RHS Garden Harlow Carr. The charity also supports emergency rescue of threatened collections in collaboration with regional plant groups and conservation partners including county plant societies and local museums.

Education and Community Outreach

Plant Heritage delivers training, workshops and public-facing activities to share skills in plant identification, propagation and documentation. Educational programmes draw on expertise from horticultural colleges and institutions like Kew, the Royal Botanic Garden Edinburgh and the University of Reading to offer courses on cultivar conservation, grafting techniques and historical provenance research. The charity works with community gardens, allotment networks, and heritage orchards to promote the planting and exchange of heritage varieties, engaging civic organisations such as the National Allotment Society and heritage trusts. Public outreach includes garden open days, guided tours at accredited collections, and collaboration with festivals and exhibitions hosted by venues like the Chelsea Physic Garden and RHS Hampton Court Palace Garden Festival. Plant Heritage also encourages citizen science projects that feed data into national inventories and that interface with digital platforms maintained by partners such as the Biodiversity Heritage Library and specialist horticultural archives.

Governance and Funding

Plant Heritage is governed by a board of trustees and supported by a network of volunteers, regional chairs and collection holders. Its governance framework reflects charity law and regulatory oversight in the United Kingdom and engages professional advisers drawn from horticultural institutions such as the Royal Horticultural Society and academic departments at universities including the University of Birmingham. Funding sources include membership subscriptions, donations, grants from trusts and foundations like the Esmée Fairbairn Foundation and the Garfield Weston Foundation, project funding from bodies such as the Heritage Lottery Fund, income from events and sales at plant fairs, and in-kind support from partner gardens and nurseries. The charity coordinates with corporate sponsors, philanthropic donors, and public bodies to sustain conservation programmes and to underwrite the accreditation and documentation work that preserves cultivated plant diversity across UK landscapes.
