Prunus x blireana – Although often referred to as a Flowering Plum, Prunus x blireana is actually a cross of Japanese Apricot (Prunus mume) and the Purple-Leaved Plum (P. cerasifera ‘Pissardii’). It is a sterile hybrid bearing very showy double pink blooms from early to mid spring. The foliage emerges purple and shifts to bronze-green by summer. Grows 15-18′ high. Zone 6.
Prunus incisa – The Fuji Cherry is usually found in shrub form and features 3/4″ wide white to pale pink blooms held in small clusters that emerge before the leaves. The foliage unfolds bronze tinted and shifts to green by summer, taking on orange to red autumn tones. This native of the forests of Japan is also slow growing. Grows 18′ high and wide. Hardy to zone 6.
Prunus x cistena – The Purpleleaf Sand Cherry is a cross of Prunus cerasifera ‘Atropurpurea’ and Prunus pumila. This deciduous shrub bears attractive reddish-purple foliage that nicely contrasts the pink buds that open to single white (or pale pink) blooms. Usually trained to bush form. Best in part to full sun. Grows 5-6′ high and wide. Hardy to zone 3.
Prunus spinosa – Blackthorn is a native of Europe and gets its name from the dark bark and prominent thorns or spurs. It bears abundant single creamy-white flowers before the leaves emerge in early spring. These are followed by edible black fruits (with a waxy blue bloom) that are usually picked after the first frosts. Grows 15′ high by 12′ wide. Hardy to zone 5.
Prunus mume – The Japanese Apricot is a much sought after ornamental tree with rich pink, cupped single flowers that emerge from late winter through to early spring. This native of Korea and China forms a small to mid-sized tree with a rounded crown. The apricot-like yellow fruit (about 1″) is often bitter to the taste. Grows 20-25′ high and wide. Hardy to zone 6.
