Description from Possibility Place: 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.
