Impatiens glandulifera inflorescence A. A. Reznicek inflorescence

A native of the Himalayas and an occasional ornamental in gardens; collected sparingly in Michigan in moist, disturbed sunny aeas, but more frequent, even invasive, eastward. First collected by C. K. Dodge on the streets of Port Huron, St. Clair Co., in 1912.

This species, I. balsamina, and I. walleriana have larger (especially broader) flowers than our native species, as well as much more sharply acute and serrate leaves. The flowers are usually pink, but in large colonies may vary from white to deep pink.
