Asiatic

Youngia japonica (YOUNG-ee-a juh-PON-ih-kuh)

Family: Asteraceae Non-native

Hawksbeard, in the Asteraceae (daisy) family, is a weedy summer annual herb that can be found growing as an agricultural or environmental weed, and often persisting year-round. Seedlings form a rosette resembling a small sowthistle ( Sonchus spp.) but leaves are hairy. Upper leaves are more linear and lack a stalk, and a milky sap is emitted when leaves are torn. In contrast to dandelion, narrowleaf hawksbeard plants have leaves on the flowering stem, and plants can become highly branched. In the rosette stage (i.e., before the flowering stem has bolted upward), it is much trickier to differentiate between narrowleaf hawksbeard and dandelion. The inflorescence stalk is generally leafless (but occasionally with up to 3 leaves), branched at the top, and 6 to 15 inches (occasionally to 3 feet) tall. Flowers are yellow, and dandelion-like but only about 1/2 inch in diameter. Seed heads are dandelion-like, about 1/4 to 1/2 inches in diameter, and seeds are wind dispersed. Do not let plants go to seed. Hawksbeard appears to be well managed by available pre-emergence herbicides; however, herbicide efficacy rankings for this species are based on limited experimental data. Insects, Diseases, and Other Plant Problems: This plant is weedy and listed as invasive by the NC Invasive Plant Council
