Common Pear is a large ornamental rapidly growing to about 45 feet tall and 20 feet wide. It takes on an upright, pyramidal form when young, becoming more oval and spreading with age. It grows best in full sun but will tolerate partial shade. Likes moist and well-drained soil but is easily adapted to various stressors, including acidic and alkaline Ph, restricted growth space, pollution, drought, and pruning.

Callery pear has a reputation for poor branching habits, leaving itself vulnerable to major windthrow or ice-load damage. Near vertical, co-dominant central leaders with acute crotch angles and extremely weak attachments must be thinned on a regular basis to ameliorate this liability. Branches remaining after this recommended biannual pruning will be stronger and resist storm damage more readily than those in an unattended, overgrown tree. [2]

Flowers in spring are showy, white, to 3 inches inflorescences, mid to late April for about 1 week. Foliage is green to dark green, glossy, alternate, ovate to orbicular, fluttering. Fall color is variable and generally not showy, ranging from purple, orange, yellow to red. Color does not develop until late season, November and December.

Callery pear, from a graft, is 85 years old [2]
