RHS Plant Finder is a comprehensive register published by the Royal Horticultural Society documenting cultivated plants available in the United Kingdom and Ireland. The register aggregates nursery records, herbarium data, and horticultural literature to provide identification, availability, and provenance information for ornamental and garden plants. It serves gardeners, botanists, conservationists, and horticultural businesses as a reference linking plant names to suppliers, collections, and cultivars.

History

The initiative originated within the Royal Horticultural Society during the 1990s, drawing on institutional practices established by the Royal Botanic Gardens, Kew, the Natural History Museum, London, and historic cataloguing traditions from the Linnean Society of London and the Royal Society. Early editions were influenced by taxonomic standards promoted at the International Botanical Congress and by nomenclatural work from botanists associated with the Royal Botanic Garden Edinburgh, Kew Gardens researchers, and curators at the Hunterian Museum. Institutional collaboration extended to county floras compiled by contributors linked with the Botanical Society of Britain and Ireland and with horticultural records from long-established nurseries such as those associated with the Chelsea Flower Show. Over successive editions the project integrated data practices common to repositories like the Biodiversity Heritage Library and the Natural History Museum collections teams.

Scope and Content

The register lists cultivated taxa across genera recognized by taxonomists working in institutions such as Royal Botanic Gardens, Kew, Missouri Botanical Garden, Smithsonian Institution, Royal Botanic Garden Edinburgh, and university herbaria at University of Cambridge, University of Oxford, and Royal Horticultural Society collections. Entries include accepted names, synonyms, cultivar names, breeder and nurseryman attributions, and supplier records from commercial firms with histories linked to Hillier Nurseries, David Austin Roses, and historic plant introducers associated with the Victorian era. The publication covers woody plants, perennials, annuals, alpines, and greenhouse species, referencing standards set by the International Code of Nomenclature for algae, fungi, and plants and drawing on nomenclatural judgments comparable to those published by contributors to the Flora Europaea and regional floras such as the Flora of North America. The register also records conservation status notes influenced by assessments prepared by organizations such as the International Union for Conservation of Nature and national botanical conservation initiatives coordinated with the Plant Heritage charity.

Access and Editions

Initially issued as a printed volume, later editions migrated to searchable formats paralleling digital transitions seen at institutions like Royal Botanic Gardens, Kew and the Natural History Museum, London. Editions correspond chronologically with catalogues of major horticultural events including the Chelsea Flower Show and publication timelines of seed companies and nurseries historically represented at the RHS Chelsea and RHS Hampton Court Palace Garden Festival. Libraries and archives such as the British Library, university libraries at University of Manchester and University of Edinburgh, and municipal record offices hold physical copies, while searchable databases reflect digitization practices similar to projects at the Biodiversity Heritage Library and the Global Biodiversity Information Facility. Special editions and updates have coincided with anniversaries of organizations like the Royal Horticultural Society and with collaborative compilations involving the Gardeners' Chronicle and sector journals.

Impact and Reception

Horticultural societies, professional nurseries, botanical gardens, academic botanists, and conservation bodies have cited the register as authoritative for sourcing cultivars and verifying nomenclature, similar to the role played by resources from the Royal Botanic Gardens, Kew and the International Plant Names Index. Garden writers featured in outlets such as the Gardeners' World programme, contributors to the BBC Gardeners' World Magazine, and commentators from the Times Literary Supplement and the Daily Telegraph have referenced it when discussing plant availability and heritage cultivars. Academic citations appear in journals connected to the Royal Horticultural Society and to university departments at University College London and University of Oxford. Botanical conservation initiatives, including ex-situ programs coordinated with the International Union for Conservation of Nature and national seed banks, have used the data for provenance tracing and rare cultivar recovery projects.

Methodology and Criteria

Compilation methods draw on specimen-based verification practices used by herbaria at Royal Botanic Gardens, Kew and the Natural History Museum, London, field records contributed by county recorders associated with the Botanical Society of Britain and Ireland, and documented supplier evidence from registered nurseries and plant breeders like those linked to RHS Trials and cultivar registration authorities. Taxonomic treatment follows nomenclatural standards set at the International Botanical Congress and aligns with databases maintained by institutions such as the International Plant Names Index and the Germplasm Resources Information Network. Inclusion criteria emphasize verifiable commercial availability in the United Kingdom and Ireland, cultivar registration or documented provenance, and cross-referencing with archival nursery catalogues and herbarium vouchers housed at organizations including the Royal Botanic Garden Edinburgh and the Natural History Museum. Peer review and editorial oversight are conducted by specialists associated with the Royal Horticultural Society and collaborating botanical institutions.

Related Projects and Collaborations

The register interfaces with botanical and horticultural initiatives such as plant trials administered by the Royal Horticultural Society, conservation schemes run by Plant Heritage, and ex-situ conservation efforts coordinated with the Seed Conservation Strategy and partners at the Millennium Seed Bank Partnership. Data-sharing relationships mirror collaborations among the Global Biodiversity Information Facility, the Biodiversity Heritage Library, and institutional databases maintained by the Royal Botanic Gardens, Kew and the Natural History Museum. Academic collaborations involve departments and research centres at University of Oxford, University of Cambridge, Imperial College London, and the University of Birmingham, while industry linkages extend to historic nurseries and breeder organizations represented at events like the Chelsea Flower Show and RHS Hampton Court Palace Garden Festival.
