Larry Stanley who has more than 30 years of experience in the nursery industry and founded Stanley and Sons Nursery with his father in 1976 discovered Stanleys Dwarf. It was originally planted as a Christmas tree on 114 cm centers with 3000 other seedlings, when the other trees were cut down or dug, this plant was only 20 cm high and 30 cm across. Strangely enough, Stanley does not list this; maybe it should be Stanley’s mystery, Quoted directly from Larry Stanley “Stanley's Dwarf is still not a very good cultivar we do not propagate it”.
