Physostegia virginiana (Obedient Plant)

This native wildflower is easily grown in average to moist well-drained soil in full sun. Plants form erect clumps and naturalizes in gardens. Stiff, square stems feature dense spikes of pinkish, snapdragon-like flowers which bloom throughout the summer. Blooms from bottom to top on each spike. Leaves are narrow, lance-shaped and sharp-toothed.

Additional Information:
Genus members are commonly called obedient plants because each individual flower will, upon being pushed in any one direction, temporarily remain in the new position as if it were hinged. Sometimes also commonly called false dragonhead because the flowers are suggestive of those of dragonhead (Dracocephalum).
