Compass Plant is a tall, deeply tap-rooted prairie wildflower that can reach 10 feet, with large, deeply cut leaves that orient north-south (hence the name) and masses of yellow sunflower-like flowers. Its deep roots can penetrate 15 feet into prairie soil. The seeds are important food for goldfinches and other prairie birds, and the resin has been used as chewing gum.
