Creeping Bellflower (Campanula rapunculoides)

Campanula rapunculoidesPhotographed October 2.

A European garden flower escaped from cultivation, often in yards of older homes where it had originally been planted. It is easily identified by its stalks of large dangling blue-violet bells, all arranged on one side of the stem. This plant grew at the edge of a sidewalk in Beechview in the shadow of a tall hedge.

Although Gray says it blooms in July and August, this plant was part of a colony happily blooming in early October.

From Gray’s Manual:

CAMPÁNULA [Tourn.] L. BELLFLOWER. Calyx 5-cleft . Corolla generally bell-shaped, 5-lobed. Stamens 5, separate; the filaments broad and membranaceous at the base. Stigmas and cells of the capsule 3 in our species, the short pod opening on the sides by as many valves or holes. —Herbs, with terminal or axillary flowers. (A diminutive of the Italian campana, a bell, from the shape of the corolla.)
