The invasive Callery Pear

The problem!​​

The callery pear (Pryus calleryana) is a medium- sized tree that has commonly been used as an ornamental due to its’ showy white flowers in early spring and beautiful fall foliage. This rapidly growing tree provides shade around homes and commercial property and birds consume the fruit. There are both thorned and thornless cultivars. The Bradford pear or Chanticleer pear are common cultivars that show resistance to disease and pests and tolerate a range of environmental conditions.
