Prunus domestica — European plum

Facts
European plum is also known as "prune-plum" because its fruits, with high sugar content, can be dried to produce prunes. This is a small tree, growing to 10 feet or 3 m tall, which produces abundant white flowers in early spring that are visited by bees and butterflies but can also self-pollinate. The sweet fruits attract many animals, who may help this species disperse and naturalize outside the garden.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.

From Flora Novae Angliae dichotomous key
6. Prunus domestica L. E
European plum. CT, MA, NH. Roadsides, abandonded homesteads, forest borders. Prunus domestica is similar to P. insititia. In addition to the characters used in the key, they can be separated by characteristics of their fruit. Prunus domestica has fruits 40–75 mm long with a conspicuously compressed and keeled endocarp that separates from the mesocarp (i.e., flesh). Prunus insititia has fruits (10–) 15–25 mm long with a somewhat compressed and scarcely keeled endocarp that adheres to the mesocarp.
Native to North America?
No
Sometimes confused with
- Prunus persica:
- flowers and fruits sessile or subsessile and ovary and drupe densely pubescent (vs. P. domestica, with flowers and fruits borne on evident pedicels and ovary and drupe glabrous).
- Prunus cerasifera:
- hypanthium glabrous, leaf blades glabrous on the abaxial surface or sparsely pubescent along the midvein, flowers 20–25 mm in diameter, and drupes 20–30 mm in diameter (vs. P. domestica, with the hypanthium pubescent, leaf blades pubescent on the abaxial surface, flowers 10–20 mm in diameter, and drupes 40–75 mm in diameter).
