Relevance to Humans and Ecosystems
Physostegia virginiana (obedient plant, obedience, or false dragonhead) is a species of flowering plant in the mint family, Lamiaceae. It is native to North America, where it is distributed from eastern Canada to northern Mexico. Physostegia are known commonly as obedient plants because a flower pushed to one side will often stay in that position. The name false dragonhead refers to the dragonheads of the related Dracocephalum, a genus to which the plant once belonged.
It is a rhizomatous perennial herb producing clumps of stiff, squared stems 2 to 4 feet tall. The leaves are lance-shaped and toothed. It has long, dense spikes of lipped, pinkish, "snapdragon-like" flowers in the summer.
It is considered a good plant for adding late-season flowers to a garden. Fertile soils produce robust growth and wide spreading, and the plant may require staking. When it grows tall it has a "tendency toward floppiness" that can be controlled with pruning. It can be aggressive and dominate a landscape.
