Impatiens capensis

Impatiens capensis, also known as orange jewelweed, common jewelweed, spotted jewelweed, or orange balsam, is a plant species native to North America. It belongs to the Balsaminaceae family and is known for its distinctive orange flowers and its method of seed dispersal.

Description

Impatiens capensis is an annual plant that typically grows between 0.5 and 1.5 meters in height. The leaves are alternate and toothed, while the flowers are orange with a three-lobed corolla. One of the petals features a long, nectar-filled spur that extends backward, resembling a tail.

Distribution and Habitat

Impatiens capensis is found throughout North America, particularly in the eastern and northern regions. It thrives in moist, semi-shaded areas, often along riverbanks, streams, and other wetland habitats.

Reproduction

The plant reproduces through a unique method known as explosive dehiscence. When the mature seed pods are disturbed, they 'explode' and eject the seeds up to several meters away. This mechanism allows for effective seed dispersal and colonization of new areas.

Uses

Historically, the plant has been used in traditional medicine by Native American tribes. The juice from the stems is believed to relieve the symptoms of poison ivy and other skin irritations.

Conservation Status

While Impatiens capensis is not currently considered threatened or endangered, it is susceptible to habitat loss due to human activities such as development and pollution.
