Soil: Mesic(Medium) to Xeric(Dry)
Flowers: The flowers grow in .5"-1" long cylindrical spikes and bloom in a ring around the spike. The individual flowers are 1/6" long with one main heart-shaped petal and 4 narrow petal-like structures.
Leaves: The sparse leaves are divided into 3-7 leaflets each 1/2" - 3/4" long.
Like the White Prairie Clover this plant has a vase-shape as well, but the leaves are finer in texture and the flowers are purple or magenta and are attractive to butterflies and bees. The plants grow well on sandy, gravelly soils or mesic and garden soils. Beautiful in bouquets!
Medicinal Uses: Tea from ground taproot has been used as a fever remedy and as a healthful drink to ward off illness. Tea from leaves was used on wounds. The Pawnee used it as a prophylactic.
Other Uses: It moves nitrogen from the air into the ground, which improves the soil.
