Virgin's Bower (Clematis virginiana)
A long vine, growing over shrubs and fences by means of the turning and twisting of its leaf-stalks. In places it makes a tangle over alders, hazels, and other bushes, twining into a veritable bower. Its hoary, plumed seeds are ripe in September, and, if near one's house, press themselves flat against window-screens. Wet, springy soil, river-banks, etc. New England to Georgia and westward to Kansas. (See illustration, p. 393.)
