About

Youngia japonica, commonly called Oriental false hawksbeard, is a species of flowering plant in the family Asteraceae. Native to eastern Asia, it is now found as a weed nearly worldwide.

Where it grows

Youngia japonica is native to eastern Asia in China and Japan. However, it has been spread far from its initial range, and is now found as a non-native species nearly worldwide. It is present in Africa, Australia, Europe, North America, and South America. In the United States, it is spreading rapidly, although it is largely restricted to areas in the Southeast. It grows well in response to human disturbance, and is found in areas such as roadsides, cultivated fields and in lawns. In China, it is found in a variety of natural and disturbed habitats. It is known to penetrate into intact natural communities as an invasive species in the United States.
