Oriental false hawksbeard, Youngia japonica, is native to eastern Asia, but it has spread far from its initial range, and is now found as a non-native species nearly worldwide. In the United States, it is spreading rapidly, although it is largely restricted to areas in the Southeast. It grows well in disturbed soils, and is found in areas such roadsides, cultivated fields, and in lawns. It is also known to penetrate into intact natural communities as an invasive species in the United States. This member of the Aster family and cousin to the dandelion, is considered an annual, but in our area it can persist and bloom almost year-round, although it seems to favor cooler weather. In favorable conditions it can reach 2 feet in height, but is typically a bit shorter.

The key to controlling it is to pull it before it sets seed. Seeds are wind dispersed. Mulching bare soil is key to keep it from sprouting. A preemergent such as corn gluten, when applied appropriately can lessen its spread.

Even though false hawksbeard is an invasive weed, it has its good points. It is quite edible, and considered a tasty potherb. Medicinally, it has anti-cancer properties that are presently being studied. Many pollinating insects make use of its nectar.
