Description

Prunus pseudocerasus var. cantabrigiensis flowers

A small bushy tree growing to at most 8 m (26 ft), it generally has reddish buds, shell pink 2 cm (0.8 in) flowers and typical red (if a bit pale) 1.5 cm (0.6 in) cherries.^[2] It can be distinguished from its congeners by certain traits; its 7–16 cm (3–6 in) leaves are broadly obovate, with an acuminate tip, flat and serrated, its inflorescences are corymbose or subumbellate, with at least three and as many as seven flowers, and its branches and peduncles are pubescent.^[3][2]

Uses

In China it has been cultivated for its edible (if tart) fruit for around 2000 years.^[2] In Japan it is favored as an ornamental tree for its tendency to bloom, flowers before leaves, earlier than the Japanese cherry Prunus serrulata.^[4] A tetraploid with 2n=32 chromosomes, it is used as rootstock for other flowering cherries. It is the parent of a number of hybrid cultivars.^[5][4] It is resistant to the fungal disease cherry leaf spot.^[6][7] P. pseudocerasus is near extinction in the wild due to anthropogenic activities.^[8]
