Dalea

Not to be confused with Dahlia, in family Asteraceae

Dalea is a genus of flowering plants in the legume family, Fabaceae. Members of the genus are commonly known as prairie clover^[2] or indigo bush.^[3] Its name honors English apothecary Samuel Dale (1659–1739).^[4] They are native to the Western hemisphere, where they are distributed from Canada to Argentina.^[5] Nearly half of the known species are endemic to Mexico.^[6] Two species of Dalea (Dalea ornata and Dalea searlsiae) have been considered for rangeland restoration.^[7]
