Physostegia virginiana: 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.
