Irina Kadis contributed to this Plant Profile.
Prunus alleghaniensis is a rare small tree that can grow as a shrub and sometimes form extensive thickets. Its height is up to 4-5 m; young shoots are pubescent, becoming lustrous red during the first winter, then darkening to nearly black. It may grow either unarmed or armed with spinescent lateral branchlets. Leaves are rather thick and firm, dark green above and paler below, finely and sharply serrate with glandular teeth, furnished with two large, rather conspicuous glands at base; young leaves pubescent, mature ones puberulous on upper surface. Their lower surface either glabrous (with few hairs in axils of veins) or rufescent, especially along midrib and veins.
There are a number of recognized varieties of this species, one of which is also in the National Collection under the Holden Arboretum (Prunus alleghaniensis var. davisii).

Conservation, Ecology & Research
Propagation proved difficult.
Seed germination trials have never been performed at the Arnold Arboretum because of a lack of fresh viable seed.
Propagation from softwood cuttings: May-Jul in 50/50 sand-perlite, under fog or mist, with 2,500-5,000 ppm K-IBA treatment (root in very small percentages, poor rooting, don't survive).
Grafts onto P. americana, P. avium, P. mahaleb (side veneer or whip-and-tongue) take, but grow weak, with a tendency for the understock to overwhelm the scion.
Research into nursery propagation of the species and reintroduction into historical sites should be continued.
Research regarding disturbance factors that maintain the necessary open conditions should be undertaken.
