About

Dalea candida is a species of flowering plant in the legume family known by the common name white prairie clover. It is native to North America, where it can be found throughout central Canada, the central United States, and northern Mexico. It can sometimes be found outside its range as an introduced species. It grows in many types of habitats, including several types of prairie, foothills, woods, forests, and disturbed areas.

It is a perennial herb growing erect to a maximum height around 1 meter (3 ft 3 in), its taproot growing up to 5 or 6 feet (1.5 or 1.8 m) deep. The alternately arranged leaves are each composed of several narrow, gland-dotted, light green leaflets. The inflorescence is a dense cylindrical spike of flowers at the tip of each stem or stem branch.

Where it grows

It is popular with pollinators and, as it is a legume, it is a nitrogen fixer. It is classified by the USDA as a "high" nitrogen fixer, a category few native plants fit into. It is a larval host to the clouded sulphur, marine blue, Reakirt's blue, and southern dogface.

Uses

Among the Ramah Navajo, the candida variety is used for stomachache and as a "life medicine", especially for fever. A compound decoction is used to treat "snake infection" in sheep.
