Obedient Plant  is a rhizomatous perennial. It is commonly found in a variety of habitats including open meadows, prairies, stream banks, gravel bars, wooded bluff bases and railroad track right-of-ways. Tubular, two-lipped, snapdragon-like, pink to pale lilac flowers in upright terminal spikes (each to 12-18”) bloom throughout summer (late June-September) atop square stems rising to 2-4’ tall. Flowers bloom bottom to top on each spike. Species plants are noted for being aggressive spreaders in the landscape by both rhizomes and self-seeding.
