Prunus maackii aka Manchurian Cherry

Prunus maackii is a deciduous tree in the rose family. Its common names include Amur cherry and Manchurian cherry. Its native range spans the Russian Far East to Korea, including Manchuria. This tree suits cold regions better than hot ones. Gardens grow it for its bark, spring flowers, and shape. It can stand alone on a lawn or grow in groups.

Garden height estimates vary from 20–45 feet [6.1–13.7 metres]. Missouri Botanical Garden gives 20–30 feet [6.1–9.1 metres] as its usual range. Other sources describe trees reaching 40–45 feet [12.2–13.7 metres]. Spread can reach 25–35 feet [7.6–10.7 metres]. The crown is dense and rounded, sometimes with a vase shape. Growth proceeds at a moderate rate. Its glossy bark ranges from golden brown to reddish or cinnamon brown. The bark peels in strips or flakes. It gives the bare tree interest through winter.

The simple leaves grow in an alternate pattern along branches. They have an oval to oblong shape and fine, toothed edges. Each leaf is about two to four inches long. The leaves are medium green, with hairs along the midrib. They turn yellow in autumn. Small, fragrant white flowers grow in clusters called racemes. Each flower has five petals. Bloom starts in late April in some places. Chicago lists a later season, from May to June. Flowers form on the previous year's growth.

Small, round drupes follow the flowers and attract birds. The fruit changes from red to black as it ripens. Sources place ripening from August into autumn. Reports of its food value conflict. Missouri Botanical Garden reports use in jam, jelly, and juice. Chicago Botanic Garden calls the fruit inedible. These sources do not establish the safety of other plant parts. The tree also serves as a street or patio specimen.

Grow this tree in moist soil that drains well. It accepts full sun or partial shade. Full sun suits it best in northern climates. Chicago lists USDA zones 3–7; other sources report zone 2 tolerance. Heat and humidity can limit growth, even within that range. Hot summer sun may scorch the leaves. Pruning helps maintain its tree shape, and roots may girdle the trunk. Borers, aphids, and scale can cause trouble. Reported disease risks include leaf spot, dieback, and root rot. Leaf curl, powdery mildew, and fireblight are also possible.
