White Prairie-clover

Dalea candida Michx. ex Willd.

This fall-blooming prairie perennial is pollinated by many insects including flies, bees, and wasps. It is often browsed by livestock, deer, elk, and some game birds, while seeds are eaten by other bird species. Indigenous people have also used it for food and medicinal purposes. Because it can help restore nitrogen to the soil, White Prairie-clover can be important for prairie restoration or land reclamation projects.
