Description

Impatiens glandulifera, also known as Policeman's helmut, it an impressive but very invasive garden escapee in our region. It prefers to grow in moist habitats along river edges, riparian areas and wetlands.It is an annual and a prolific seed producer. Seed pods eject seeds as far as 6 meters when disturbed or touched, which can make removal difficult. This plant has a shallow and rather weak root system that can increase erosion along streams when the plant dies back in the fall. However, this also makes the plant extremely easy to hand-pull before it flowers in the spring. Pulled sites need to monitored for several years due to the longevity of the many seeds Himalayan balsam produces. Read more about alternatives to plant in the Grow Me Instead booklet for BC.
