This native plant looks like a fourth of July firework! Prairie onion has long, grass-like leaves topped with a brilliant purple globe of flowers, with a strong onion scent.  Their oval-shaped bulb is covered with a papery outer coat.  Their flower stalks with erect clusters of pink star-like flowers are attractive to small bees, flies, and butterflies.  Prairie onion grows naturally in prairies, and dry, sandy or gravelly soil.  Propagation is mostly by seeds and bulbs.  Their black seeds are contained in chambers that are picked open by birds and small mammals for food. Other common names are cliff onion and prairie wild onion.
