NB. Recommended websites for verifying the correct name of garden plants:
There are two primary resources used by botanical horticulturists for finding out the correct spelling of a name: TROPICOS, an online database of the Missouri Botanical Garden and theInternational Plant Name Index (IPNI) maintained by theRoyal Botanic Gardens, Kew.
However, professionalgardener’s are more likely to look at the Royal Horticultural database
In order to clarify the correct spelling or nomenclature for a plant they are working on.
