Dalea purpureum or Purple Prairie Clover as it is commonly known is very drought tolerant and showy, blooming all summer! The pinkish-purple blossoms on this perennial clover bloom at the base of the flower cone, and slowly ascend to the top. This wildflower was a favourite of Native Americans, which they used to treat wounds. It grows to a height of 30cm to 45 cm, should be spaced 40cm to 50cm apart in full sun to part shade.
