Growth habit & biology

Impatiens parviflora is an annual plant that can grow up to 60 centimeters tall.

The oval to broadly lanceolate leaves taper to a point. The leaf margin is serrated. The color varies from light green to dark green.

It spreads by seed, which are ejected from the fruits. This allows Impatiens parviflora to quickly colonize large areas.

The leaves and seeds are said to be edible.
