Habitat: Himalayan balsam is an herbaceous, terrestrial, annual plant that thrives in riparian zones. It can be found in wetlands, forests, gardens, yards, and on the side of the road. This species can tolerate many types of soils.

Native Range: Himalayan region of Asia

U.S. Distribution: Has been introduced to northern states on the east coast as well as the west coast, including Montana and Idaho

Local concern: Himalayan balsam competes heavily with native species and alters the behavior and composition of pollinating insects. Additionally, this species can alter water flow at high densities which increases the risk of erosion and flooding.

Other Common Names: Ornamental jewelweed, touch-me-not, Indian jewelweed, policeman’s helmet

Native look-alikes and how you can tell them apart from Himalayan balsam:

  • Jewelweed or spotted touch-me-not (Impatiens capensis): Yellow to orange flowers, much smaller in size, leaf blades more rounded with fewer serrations.
  • Pale touch-me-not (Impatiens pallida): Yellow flowers. Leaf blades more rounded, with fewer serrations.
