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

The small cherries are edible but mealy and not very palatable raw, occasionally cooked, and the species is grown mainly for its spring flowers rather than for fruit. ⚠ Kernels/pits cyanogenic.

Growing guide

Fertilizing. Prefers well-drained, moisture-retentive loam and tolerates limestone, becoming chlorotic if lime is excessive; suits the light, poor, rocky soils typical of alpine sites.

Growing tips. A true ground-hugging alpine shrub that dislikes strong winds and can die back in exposed positions — give it a sheltered spot; well suited to rock gardens and scree plantings.

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.
