In this paper, the case for the conservation of plants that have arisen in cultivation is provided and the mechanisms for extinction discussed, with examples. The approach to cultivated plant conservation over the past 30 years is reviewed and a basis for revising that approach explained. A new, far more comprehensive and rigorous method for prioritisation is proposed. This has been developed for the Plant Heritage Threatened Plants Project.
