Brief description

Impatiens capensis Meerb., common names: orange jewelweed, common jewelweed, spotted jewelweed, spotted touch-me-not or orange balsam, is an annual plant which is native to North America. It is common in bottomland soils, ditches, and along creeks. Jewelweed is an herbaceous plant that grows 1 to 1,5 meters tall and blooms from late spring to early fall. The flowers are orange (sometimes blood orange or rarely yellow) with a three-lobed corolla. It often branches extensively. The round stems are smooth and succulent and semi-translucent, with swollen or darkened nodes on some plants. The leaves are alternate and simple and have teeth on the margins. Impatiens capensis was transported in the 19th and 20th centuries to England, France, the Netherlands, Poland, Sweden, Finland, and potentially other areas of northern and central Europe. This jewelweed species is quite similar to Impatiens noli-tangere, an impatiens species native to Europe and Asia (Wikipedia contributors 2022).
