About Ligustrum obtusifolium Siebold & Zucc.
Ligustrum obtusifolium Siebold & Zucc., commonly known as border privet or Amur privet, is a species of privet. It is native to Japan, Korea, and northeastern China, specifically occurring in the Chinese provinces of Heilongjiang, Jiangsu, Liaoning, Shandong, and Zhejiang. This species is classified as 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 populations found in the South, the Great Plains, and Washington state. Along with Ligustrum ovalifolium, L. obtusifolium is one of the parent species of the widespread hybrid Ligustrum × ibolium. L. obtusifolium is a deciduous shrub that grows to 3 metres (9.8 ft) tall. Its leaves measure 1 to 6 centimetres (0.39 to 2.36 in) long and 4 to 25 millimetres (0.16 to 0.98 in) broad. Three subspecies of L. obtusifolium are recognized: Ligustrum obtusifolium subsp. obtusifolium, which is found in Japan; Ligustrum obtusifolium subsp. microphyllum (Nakai) P.S.Green, which occurs in eastern China, Korea, and Japan; and Ligustrum obtusifolium subsp. suave (Kitagawa) Kitagawa, which is native to northeastern China.
