The perennial obedient plant or false dragonhead produces blossoms in late summer and early fall. The name obedient is derived from the tendency of the flowers to stay in place if you turn them. False dragonhead comes from the fact that it resembles a snapdragon. Although some people find it invasive, it is easy to control, and has the additional benefit of attracting bees and butterflies. It is available in pink, light purple and white and grows in height from 2 to 4 feet.
