Conservation Actions

In 1978 local scientists conducted propagation experiments and this resulted in the establishment of young plants in a nursery, however these are thought to have been discarded. This variety is known to be in cultivation in three gardens in the UK; the Royal Botanic Garden Edinburgh, Royal Botanic Gardens, Kew, and Bedgebury National Pinetum.
