Found only in Oregon and California, the Klamath Plum tree is hardy only to USDA zone 7.

It is a tall shrub or small tree, reaching 25.’

It favors drier, slightly alkaline soils, full sun and will not tolerate heavy shade.

Spreading by suckers, the Klamath Plum quickly forms thickets and is often associated with Hawthorne.

The edible fruit is relished by wildlife and makes flavorful preserves but do take care not to crush the seeds as they contain cyanide.
