“The hawkweeds are a very large genus of plants with approximately 25 species in North America. Hawkweeds are members of the sunflower family and are closely related to dandelion, chicory, prickly lettuce and sowthistle. Like some of their relatives, hawkweeds can rapidly colonize and dominate forest meadows, pastures and roadsides. In addition to reproducing by seeds, hawkweeds are capable of spreading by rhizomes, stolons and adventitious root buds. These methods of vegetative reproduction and a tolerance for sites with low productivity are probably responsible for the ability of these plants to quickly establish and dominate new areas. ”
