Subhirtella cherry (Prunus subhirtella). It is capable of reaching a height of 8m at maturity, but usually attains rather less. It bears white to pink flowers which may emerge intermittently from autumn through to spring.
The flowers are pink in bud, semi-double, 1cm across, pendulous, held in small clusters and white when fully opened, although they acquire pink tones as they fade. The flowers have a delicacy and charm completely unknown to the more showy spring-flowering cherries. The leaves are 7cm long, oval and sharply toothed. The autumn leaf colour is better than in many other ornamental cherries.
