Urban species #234: Callery pear
Pyrus calleryanaThe
sugar maples have long dropped their leaves, the
red maples' "October glory" has faded; even most of the
oak trees have shed their foliage. But a line of street trees stubbornly hangs on, each tree bearing shiny, heart-shaped leaves, mostly green at the bottom, blazing to yellow and red toward the top. I was aware of these trees but despaired in ignorance of their identity. Then a group of us went to the
Mount Auburn cemetery, where the exquisite landscaping is carefully composed and each tree bears an identification tag. We saw one of these trees, its leaves still multicolored in a sea of bare wooden skeletons, and rushed to read its tag.
The callery pear is a cultivated variety of a tree native to China. Along with its foliage, colorful and persisting into late fall, it is valued for its profuse blossoms, similar to those produced by trees in the same family:
roses, cherries, and
apples. It also resists most of the stresses of urban living, such as root compression and pollution. However, it is vulnerable to storm damage, and many of the individuals I've examined show scars from limbs having broken off in the wind. The most surprising thing about this pear tree is its fruit--by definition they are pears, but they are tiny round berries. They aren't brightly colored, or much favored by wildlife (though
birds and squirrels will eat them), and a fruitless cultivar of the tree called "Bradford pear" is often planted. Many landscapers consider the callery pear to be overused.

Location: Aspinwall Ave, Brookline.
