Once you know the name, you can check it online, or in a paper copy of the RHS Plant Finder
– as a rough indication, the fewer nurseries that are stocking your plant, the more likely it is to be rare enough to register within the Plant Guardian scheme. If it has more than five entries it is unlikely to be Threatened, if it has just one there is a good chance it is. If you are not sure, register it anyway, we check all the plants that you input!
When you register
the plant online, we will check it for you, and let you know if it qualifies or not. We use the methods used in the Threatened Plants Project
to assess cultivars and a combination of the TPP methods and the IUCN Red list
