Description

Pink and white blossoms on a ornamental pear tree.

The ornamental pear tree (pyrus calleryana) and its cultivars possess characteristics that make them ideal as landscaping centerpieces. With an abundance of showy flowers in warmer seasons and striking leaf color in the cooler ones, ornamental pears bring beauty year round. In addition to their ornamental attributes, they are relatively simple to care for, as well as utilitarian.

Most types of ornamental pear trees have a rounded shape and erect habit, with a high or low spreading canopy. However, characteristics vary depending on the cultivar. Some, such as the "Aristocrat" (Pyrus calleryana "Aristocrat") and the "Redspire" (Pyrus calleryana "Redspire"), both found in USDA zones 5 to 8, have a conical shape, and the "Capital" culitivar (Pyrus calleryana "Capital"), which grows in USDA zones 4 through 8, is a columnar tree. The Chanticleer pear (Pyrus calleryana "Chanticleer"), also found in USDA zones 4 to 8, has a pyramidal shape with minimal spreading.

Ornamental pear trees grow best under full sun. Two cultivars, "Redspire" and "Capital," can take full sun or partial shade. All grow in a wide range of soil types and pH levels, and, though they favor moist soil, will tolerate hot and dry conditions. Among the ornamental varieties, the "Chanticleer" is more resistant to freeze. Ornamental pears are typically resistant to fire blight, oak root fungus and verticillium wilt but susceptible to sooty mold and white fly. In addition to these diseases, two varieties -- the "Capital," and "Fauer" -- are also susceptible to thrip.
