Astragalus barrii
Barr's milkvetch (Astragalus barrii) is a low, mat-forming perennial herb in the pea family, native to the northern Great Plains of the USA, growing on buttes and badlands. It needs full sun, excellent drainage and very little water.
Astragalus barrii is a species of flowering plant in the legume family known by the common name Barr's milkvetch. It is native to the United States, where it is a "regional endemic", occurring in parts of southwestern South Dakota, northeastern Wyoming, southeastern Montana, and Nebraska.
This mat-forming perennial herb grows only about 4 inches in height. The leaves are each made up of three lance-shaped leaflets. The herbage is coated in white hairs which are dolabriform, or shaped like the head of an ax. The inflorescence contains iridescent pinkish purple flowers with petals up to 1.7 centimeters long. The fruit is a legume pod up to 8 millimeters in length. Blooming occurs in late April through mid-June; April flowering generally only occurs in years with light snowfall.
