Prunus glandulosa aka Chinese Bush Cherry

Prunus glandulosa is a small shrub in the rose family. Gardeners call it dwarf flowering almond or Chinese plum. Its native range spans central and southern China to southwestern Korea. It sheds its leaves each year and grows at a moderate pace. Garden plants reach 3–5 feet [0.9–1.5 metres] tall. Most spread 3–4 feet [0.9–1.2 metres] wide. The RHS gives a wider spread of 5 feet [1.5 metres]. Plants take about five to ten years to reach full size.

Several stems form an open, rounded bush with upright shoots. The thin stems can give it a loose, untidy look. Pale green leaves grow in turn along the stems. Each simple leaf has a long, narrow or oval shape. Fine teeth line the edges, with glands on the stipules. Leaves can reach about 4 inches long. Neither the bark nor the fall leaves add much interest.

Small white or pink flowers crowd the shoots in spring. Chicago records bloom in March and April; UConn lists April. The RHS places flowering in mid to late spring. Each flower measures about half an inch across. The species bears single flowers; named forms may differ. Small, round drupes turn dark red to purple-red. Each fruit holds one large seed, though fruit can be scarce. The shrub attracts birds and hosts eastern tiger swallowtail larvae.

Grow it in full sun, though it tolerates some shade. It suits moist soil that drains well and has moderate fertility. It accepts sand, loam, clay, and chalk across a broad pH range. Avoid wet ground, though plants can cope with some drought. Sources place it in USDA zones 4–8 and RHS H6. Use it in borders, groups, containers, or near a patio. Its main garden value lies in the spring flowers. It draws less notice once summer arrives.

Aphids and caterpillars can attack it, including tent caterpillars. Diseases include leaf curl, silver leaf, canker, and blossom wilt. Honey fungus also poses a risk. The RHS flags it as a high-risk host for Xylella. PFAF records preserved or pickled fruit and edible seeds. Yet stems, leaves, and seeds contain cyanide-forming compounds. Wilting makes these parts more hazardous to people and animals. Do not eat bitter seeds or fruit. Leaves and fruit also yield dyes.
