Survives zone 5 through 9
Harvest calendar
Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.
Fruit is intensely bitter and essentially unpalatable to people — though it's an important food source for songbirds, bears, coyotes, and other wildlife. ⚠ Kernels/pits cyanogenic (seeds contain hydrocyanic acid).

Growing guide
How it spreads. Strongly suckering; roots can spread up to 15 m (50 ft) from the parent plant, sending up shoots that form dense thickets.
Growing tips. Fast-growing but short-lived (30–40 years); tolerates sun or partial shade and is drought-tolerant once established; blossoms are a nectar source for Sara orangetip, silvery blue, and Lorquin's admiral butterflies.
Companion planting. Host to eastern and western tent caterpillar, shared with cultivated cherries and plums — heavy infestations on wild bitter cherry thickets can spread to nearby orchard trees.
