Prunus americana Marshall
American plum, Wild plum
Rosaceae (Rose Family)
USDA Symbol: PRAM
A thicket-forming shrub or small tree with short trunk, many spreading branches, broad crown, showy large white flowers, and red plums. American plum is a small, understory tree to 35 ft. with fragrant, white flowers in showy, flat-topped clusters occuring before the leaves in spring. The fruit that follows ripens to a shiny, bright red in August or September. The short, crooked trunk – with scaly, black bark – supports a graceful, open crown. Fall foliage ranges from electric red to pale yellow.
The plums are eaten fresh and used in jellies and preserves, and are also consumed by many kinds of birds. Numerous cultivated varieties with improved fruit have been developed. A handsome ornamental with large flowers and relatively big fruit, American Plum is also grown for erosion control, spreading by root sprouts.

BenefitUse Wildlife: Plums are not a choice food for wildlife, but the plants provide valuable nesting cover and are a host to many butterflies.
Use Food: The fruits have tough, sour outer skins, but their sweet, juicy flesh is delicious, making excellent jams, jellies, preserves and pies. The plums can also be halved, then pitted and dried like prunes, spread in a thin sheet and dried as fruit leather. (Kershaw)

PropagationDescription: Prunus species may be rooted from dormant hardwood, softwood, semi-hardwood, or root cuttings. Semi-hardwood and softwood cuttings taken in summer root easiest. Germination of most seeds requires cold stratification. Some species need a period of after
Seed Collection: Collect fruit when it is filled out, firm, and its ripe color. Clean seeds from pulp and briefly air dry. (Seeds to be sown immediately in fall do not need drying.) Storage viability is maintained at 31-41 degrees.
Seed Treatment: For spring sowing, stratify seeds in moist sand for 30-60 days in a greenhouse, then cold stratify (36-41 degrees) for 60-90 days. Plant well before high temperatures.
Commercially Avail: yes
