Physostegia, the lionshearts or false dragonheads (in reference to their similarity to Dracocephalum), is a genus of flowering plants in the family Lamiaceae, native to North America (United States, Canada, northern Mexico). They are erect rhizomatous herbaceous perennials inhabiting damp, sunny places. They grow up to 2 m (7 ft) tall with purple or pink tubular flowers in racemes in summer.
The generic name comes from two Greek words, physa (a bladder) and stege (a covering), referring to the calyx, which becomes full of fruit when mature.
Physostegia virginiana is the most common species, and is known as "obedient plant".
