Callery Pear (Pyrus calleryana)
Callery pear trees typically grow from 30 to 50 feet tall, spreading 20 to 35 feet at maturity. They grow at a moderate rate in a pyramidal form, with large limbs growing upright from narrow crotches where they join the main trunk. Their numerous short branching stems on these limbs eventually cause the canopy to spread a bit with age. Pear tree leaves are shaped like elongated eggs, rounded at their base with irregularly toothed edges and pointed tips. Measuring from 1 1/2 to 3 inches long, they are a glossy light green in season, turning a gorgeious deep wine red in October just before they drop.
Individual pear blossoms are about 1/3 inch across. Pale white, they appear in delicate clusters in early spring before, or just as, the new leaves emerge. Although they have a fragrance, it is not particularly pleasant. The flowers give way to inconspicuous fruits which are obscured by the foliage. Only 1/2 inch or so in diameter, these little knobs are green at first, turning to russet or black and are interesting only to birds.
