Fall Obedient Plant Scientific Name: Physostegia virginiana History/general species info: Also known as false dragonhead, the Fall Obedient plant got its common name because flower stems can be bent to stay in place, not because of its growing habit.

Hummingbirds and butterflies with this long proboscises also visit for their nectar.
