Facts About

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.
