Abstract:Impatiens glandulifera Royle, an annual species native to India and West Himalayas, has invaded rapidly in many regions of Europe and North America. It was found to be naturalized newly in Mohe City, Heilongjiang Province, China. This species might have been introduced as an ornamental at least two years ago, and would produce large numbers of offspring by seed after one year of planting. The morphological characters, geographical distribution, biological habit, invasive hazards, and control methods were presented for species identification and control.
