An iconic prairie flower, Compass Plant is best known for its remarkable, large basal leaves that orient into a north-south direction, giving the plant its name. Individual plants may grow slowly, but are very long-lived and have been known to live for nearly 100 years. Mature plants are impressive, and produce numerous large yellow flowers along the stem, that open from June through September. Birds seek out the very nutritious seeds.
