purple prairie clover

Dalea purpurea (purple prairie clover) is a native Illinois prairie species that grows well in full sun. It has a deep taproot that helps sustain it through drought.

D. pupurea supports insects as both a food source and a host (ex. Dogface Butterfly larvae). Like the white prairie clover, D. pupurea also struggles to establish in areas of development disturbance.
