HORTICULTURAL
Plant Sale Text: Curlyheads is a lesser known native species of Clematis. Habit is more similar to a shrub than a vine. Thrives when it is allowed to clamber loosely upon a woody plant for support. Its flowers are bell-like, with petal-like sepals. Based on the shape of its flowers, a common name that has been used for this species is Granddaddy’s-pipe. The feathery, copper- brown seed heads are quite showy in the garden. Found most often in upland woods.
