Malus prunifolia — pear-leaved crab apple

Facts
Pear-leaved crab apple should probably be called "cherry-leaved crab apple" since its species name refers to the genus of cherries, Prunus. These trees grow to 8 meters (25 feet) tall, producing large, white flowers that attract many pollinating insects. The stem-stock of this species is well-suited to grafting of other apple varieties. The crab apples produced in the fall are only marginally tasty, but can be used to make jellies. Most non-human animals heartily feast on the fruits.
Habitat
Anthropogenic (man-made or disturbed habitats), forest edges, forests, meadows and fields
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.
