Takashi Kaneko (1992), for example, concluded from chromosome research that the Edo-higan cherry (P. pendula f. ascendens) was the seed parent and the Oshima cherry (P. serrulata var. speciosa), the pollen parent. The late (1985), owner of a flower shop at the entrance of the Somei Cemetery in Tokyo, pointed to the cherry nursery and its owner Gonbei Kawashima, who most probably released P. ×yedoensis.. Prunus ×yedoensis is a clonal cultivar and can be understood as a sato-zakura form (Ingram 1948). It is a successful nursery plant, easily propagated from cuttings and quickly growing to a marketable size on its own stem. Compared to the Japanese mountain cherry (P. serrulata var. spontanea) or the Edo-higan cherry (P. pendula f. ascendens), it is short-lived; an
