Allegheny serviceberry (Amelanchier laevis)
A commonly-used tree in landscapes is the Callery pear (Pyrus calleryana, above right), prized for its showy and fragrant white flowers that bloom each spring. However, these non-native invasive trees were recently banned by the PA Department of Agriculture. They can spread prolifically into natural spaces and outcompete native trees, shrubs and other vegetation. Although they provide food for wildlife, the Callery pear’s berries have poor nutritional value compared to fruits from native vegetation.
Allegheny serviceberry (Amelanchier laevis, above left, shown being planted by WPC staff and volunteers in spring 2021) is a small native understory tree. It shows white flowers early in the spring, and orange-red leaves in the fall, making it an ideal alternative to the
Callery pear. The edible purplish-black fruit in early summer is attractive to many birds.
