Can a plant actually be obedient? Why yes, there is one that can be and it just so happens to be commonly known as the obedient plant. The Obedient Plant (Physostegia virginiana) gets its name from the flowers’ ability to stay in place according to how you move them. The flowers are on each side of the spike and can act like a hinge. In this way, one can push them to the right or left, up or down, and have them stay in that position. It might change its position on its own after some time has passed, but for the time being, it will stay in the position you place it in.
That is the extent of this plant being obedient, for it can be aggressive and spread to places where you don’t want it. That is the main issue with the plant. Otherwise, one can prune it in the spring to help reduce its height. It can also be divided every two to three years to help keep this clump-forming Obedient Plant under control. Each clump can get up to 2 to 3 feet wide. Overall, the plant is tall, reaching heights of 3 to 4 feet. These heights sometimes lead to floppiness in the plants, so staking helps to keep them upright.
These plants are more of a prairie type plant, being a great perennial plant for the wildflower garden, the prairie garden, native gardens, and meadows. One can also use their color in a perennial border. The nectar will also attract butterflies and hummingbirds, so it is a possible plant for a butterfly or hummingbird garden. The plant just requires a sunny to partly shady location that has moist, well-drained soils.
The leaves are sharply toothed and lance-shaped, growing up to 4 inches in length. Square, stiff stems allow flowers to be born on four different sides. This stem is typical of the Mint Family, of which this plant is a member. When the flowers bloom, they start opening at the bottom of the spike first, moving toward the top. Flowers usually bloom from June to September, providing some summer color. They are usually pink in color, but can also be white. Individual flowers resemble the flowers of snapdragons and thus the obedient plant is also called false dragonhead. One can see these pink flowers around some of the apple trees in the IMA’s orchard.
