Habitat

Found in moist to wet conditions in light shade to partial sun. Occurs in moist, open areas in woodlands, floodplains, and partly-shaded areas of wetlands, seeps and ditches along roadsides. Common in much of its range. Tolerates prolonged flooding and often grows in shallow standing water, but can grow on moist ground as well.

Life Cycle

Germinates mid to late spring into early summer, and starts growing upright as soon as it sprouts. Begins blooming mid-summer and often continues to bloom. Rather than blooming all at once, this plant opens a few flowers at once, and then starts producing seeds incrementally while opening new flowers. If warm conditions persist longer in autumn, it will continue flowering and producing seeds longer.

Seeds are spring-loaded and are ejected mechanically from seed pods when ripe.

Plants are killed by frost and this species productivity is thus sensitive to early frost.

All stages of this plant are sensitive to moisture conditions. In a dry year, plants on drier ground will die and only those in wetlands or the wettest conditions will survive to maturity. In a consistently wet year, this plant will be able to survive on slightly drier ground.

Faunal Associations

Flowers attract both bees and hummingbirds. The seeds are eaten by larger birds.

Much of its range overlaps with Pale Touch-me-not (Impatiens pallida), which is less common but able to grow on slightly drier ground.
