Photographed
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.
