Wild Flowers of Pittsburgh

Redbud (Cercis canadensis)

A common tree in the forests around Pittsburgh, and also a favorite ornamental in urban and suburban yards. These trees were blooming in late April in open woods in Bird Park, Mount Lebanon.

Gray describes the genus and the species:

CÉRCIS L. REDBUD. JUDAS TREE. Calyx 6 toothed. Corolla imperfectly papilionaceous; standard smaller than tbe wings and inclosed by them in the bud; the keel petals larger and not united. Stamens 10, distinct, declined. Pod oblong, flat, many-seeded, the upper suture with a winged margin. Embryo straight.—Trees, with rounded heart-shaped simple leaves, caducous stipules, and red-purple flowers in umbel-like clusters along the branches of the last or preceding years, appearing before the leaves, acid to the taste. (The ancient name of the oriental Judas Tree.)

C. canadensis L (REDBUD.) Leaves pointed; pods nearly sessile above the calyx.—Rich soil, N. Y. and N. J. to Fla., w. to s. Ont., e. Neb., and Tex.—A small ornamental tree, often cultivated.
