The short answer is that I don’t know. It did make it to the USA, it’s listed in the Southern California Camellia Society Camellia Nomenclature, but whether it is currently being grown for sale is the key question, it dates from 1958 and very many varieties have come along since and likely elbowed it aside. You could try contacting the American Camellia Society perhaps.
