Facts
Spreading cotoneaster hails from China, but is planted widely as a low-lying shrub for ground cover or borders. In New England, it is a common garden mainstay, but has become naturalized in its favorite dry, sandy habitats along Cape Cod. Among its shiny, deep green leaves, look for tiny pink flowers to bloom in early Spring; you'll need to look very closely to realize that these flowers are members of the rose family. Later in summer, though, cotoneaster flowers will mature into bright red fruits (pomes), which are eaten by birds and small mammals.
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.
