Border Privet

Ligustrum obtusifolium (border privet or Amur privet) is a species of privet, native to Japan, Korea and northeastern China (Heilongjiang, Jiangsu, Liaoning, Shandong, Zhejiang). The species is considered invasive in parts of the United States. It has become very common in southern New England, the mid-Atlantic States, and the Great Lakes regions, with scattered occurrences in the South, the Great Plains, and Washington state. With Ligustrum ovalifolium it is a parent of the widespread hybrid Ligustrum × ibolium.
