This hardy plant is a classic of the dry prairie, and it is one of the few shrubby plants that grow on the prairie where most shrubs traditionally were eliminated by frequent fires. It has attractive purple blossoms on dense florets and its leaves are thick and silvery green. It grows to a height of between 1 and 3 feet. It has a very deep taproot which allows it to thrive in dry conditions and to survive prairie fires.
Blooms: June through August
