Impatiens capensis

Summary ⁷

Impatiens capensis, the orange jewelweed, common jewelweed, spotted jewelweed, spotted touch-me-not, or orange balsam, is an annual plant native to North America. It is common in bottomland soils, ditches, and along creeks, often growing side-by-side with its less common relative, Yellow Jewelweed (I. pallida).

Comments ⁸

The attractive orange flowers glisten in the sunlight, hence the name 'Jewelweed.' The other Jewelweed in this genus is Impatiens pallida (Yellow Jewelweed). The latter has similar foliage, but its flowers are pale yellow. The Jewelweeds have a muciliginous sap that is supposed to soothe skin irritation caused by Poison Ivy and Stinging Nettle. This sap also has fungicidal properties and has been used to treat Athlete's Foot. The cultivated Impatiens of the horticultural industry have been introduced from such areas as East Africa and New Guinea. They rarely escape from cultivation and are not considered a significant threat to native habitats.
