Yellow hawkweed is a creeping perennial of low maintenance turf, roadsides and native areas. It can be an indicator of low soil fertility or slightly acidic soils. Hawkweed spreads by stolons and rhizomes creating colonies that form patches. The leaves lay flat to the ground and overlap and will smother non-vigorous turf. All parts of hawkweed are conspicuously hairy and, like dandelion, will exude a white milky sap when broken. Bright yellow flowers form in clusters at the top of the 10-20 inch hairy mostly leafless stalks.
