False Dragonhead (Physostegia viginiana) is also called the Obedient Plant. Notice the way the flower buds line up perfectly in a column. If you twist the bloom, it will stay put, being obedient. For this reason, and because they are long-lasting, the plant is often cultivated for cut flower arrangements.
False Dragonhead blooms from July-October, favors moist habitats, and can grow over six feet tall. It is a member of the Mint family.
