Common Hawkweed

The common hawkweed, <em>Hieracium lachenalii</em>, is a flowering plant belonging to the family Asteraceae, the daisy family. Its known range includes the United States, where it may be found as a non-native introduction, as many hawkweeds have naturalized broadly beyond their native European ranges. As a member of the genus Hieracium, <em>Hieracium lachenalii</em> is a perennial herb typically recognized by its dandelion-like yellow flower heads and rosette of basal leaves. Hawkweeds are known for their complex taxonomy and tendency toward apomixis, the production of seeds without fertilization, which has led to the description of numerous microspecies within the genus. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
