The dark pink petals (10 Ă— 12 mm) show an even darker pink at the edges and tip. Prunus 'Collingwood Ingram' has an erect tree shape (Van Trier 1990). Kurile cherry (synonyms Prunus nipponica var. kurilensis (Miyabe) Wilson, P.Ă— kurilensis, chi-shima-zakura) is a variety of P. nipponica that grows in even colder regions, the Kuriles, Sakhalin, and mountainous and . It was described in detail by Kingo Miyabe in 1890. In the West it often is presented as a hybrid, which it is not. According to (Yashiro 18211841), it has been cultivated in Japan since at least the early
