Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

The small (about 5 mm) cherries are edible but thin-fleshed and grown mainly for ornament rather than fresh eating; in parts of Korea and Japan the salted flowers are occasionally used as a fragrant garnish. ⚠ Kernels/pits cyanogenic.

Spacing
450 cm (177 in) apart — about 20 m² (218 sq ft) per plant
Leaf shape
Ovate to obovate or elliptic, 4–8 cm long, with sharp double-serrated margins and downy hairs along the veins and midrib beneath.
Root system
Worth knowing that in cultivation this is usually the rootstock's root system, not the species' — most Prunus are sold grafted, and vigour, suckering and soil tolerance follow the stock rather than the top. On its own roots the species is shallow-rooted, with the bulk in the top 40–60 cm spreading well beyond the canopy, so it dislikes cultivation underneath and competes badly with grass.
Fruit description
Small, roughly pea-sized (about 5 mm) cherries, each carrying one large stone relative to the fruit's size, ripening in August.
Propagation
Seed requires 2–3 months of cold stratification and is best sown as soon as ripe, though germination can take up to 18 months; also by half-ripe heel cuttings in July-August, softwood cuttings in spring/early summer, or spring layering.
Pollination
Hermaphrodite, insect-pollinated flowers — self-fertility isn't specifically documented for this species

Growing guide

Fertilizing. Prefers well-drained, moisture-retentive loam with some lime — it becomes chlorotic if over-limed — and grows best in full sun to light shade.

Growing tips. Hardy to USDA zones 4–8; the fine-grained, heavy wood has traditionally been used for furniture and carving.

About the data

Zone figures are typical published ranges — microclimate, drainage and siting shift them by a zone in either direction. Store links are found by an automated search, refreshed every six weeks. Availability is seasonal; stock and prices are not tracked.
