I believe most of the Washington cherry trees are the cultivar 'Kwanzan.'
They
were a gift from the people of Japan.
'Kwanzan' is hardy up to Zone 6, and is still widely sold in nurseries.
However, it is somewhat disease and insect prone, and there are newer
varieties
which are tougher, and also more suitable for bonsai.


I think I recall reading that the National Park Service grows replacements
for the DC trees and replaces them as needed?
