The obedient plant typically grows to a height of three to four feet. Its flowers are tubular and resemble snapdragons, arranged in dense spikes, with each flower about 1 inch long. The colors range from pink to pale lilac. The leaves are lance-shaped, growing in opposite pairs along the stem, with each pair rotated 90 degrees from the previous one. They are about four to five inches long and one to two inches wide, with serrated edges. Obedient plants prefer full sun to partial shade and thrive in moist, well-drained soils. They are quite adaptable and can grow in a variety of soil types, including loam, clay, and rocky soils. Often found in wetlands, prairies, and meadows, they can tolerate both drought and poor drainage. (July)
