Prairie Dock has a tall central stalk that ends in sprawling flowering branches. It has large yellow, sunflower-like blooms that occur late summer to early fall and last about a month. It has dramatic, attractive clumps of basal leaves that are dark green, ... heart-shaped and nearly 2 feet long and 1 foot wide. It is slow to establish but very long lived. Its flowers attract a number of pollinators, and its seeds are a food source for many small birds.
