    Prairie-Dock is a major prairie forb, also of native meadows farther east. It gets its name from its large, coarse, oval or heart-shaped leaves that grow about 1.5 to 2 feet long at the base of the plant. It sends up tall scapes to 6 to 9 feet high with the yellow sunflower-like flowers that bloom in July into September near the top. It forms a taproot and sends out some rhizomes that slowly increase the clump. Its native range is from the southeast tip of Ontario & Ohio to Minnesota down into Arkansas, Mississippi, and South Carolina in wet to mesic soils. It is sold by a good number of native plant nurseries in the Midwest for prairie restorations and naturalistic, native plant landscapes.
