Spotted touch-me-not, also called jewelweed, is a soft plant, much-branched, with watery stems. It is common along streambanks and other moist habitats.
The flowers are orange with red or reddish-brown spots; overall, the flower is shaped like a cornucopia, with 3 unequal sepals, 2 of them small, the third a sack with a spur; 5 petals, appearing as 3 (because the lateral petals are joined), each with 2 lobes; the stamens are joined to the stigma; each flower hangs from a slender stem. The conical portion of the flower is usually about twice as long as it is wide.
Blooms June–September.
The leaves are alternate, soft, egg-shaped, bluish green, coarsely toothed, to 3½ inches long.
The fruit is a slender capsule, which, upon drying or when touched, contracts, coils, and splits explosively, casting seeds far away in all directions.
Similar species: Pale touch-me-not (I. pallida), also called jewelweed, has lemon yellow flowers, and the conical portion of the flower is about as long as it is wide, with a shorter spur. Without seeing the flowers, it is almost impossible to distinguish between the two species.
Height: to 5 feet.

Statewide.
Habitat and Conservation
Occurs in damp, low woods; banks of streams, rivers and springs; swampy places; edges of ponds; ravine bottoms; bases of bluffs; and other moist, disturbed areas.
Status
Native Missouri wildflower.
Human Connections
Many believe that rubbing the juice from the foliage on the skin will prevent and even cure a poison ivy infection as well as take the sting out of stinging nettle and the itch from chigger bites.
Native Americans had many medicinal uses for these plants.
Today people cultivate them as ornamentals in native wildflower gardens.
Ecosystem Connections
Our two species of jewelweeds are often found growing together, but apparently they do not hybridize. They both have different pollinators: Spotted touch-me-not is visited by hummingbirds, pale touch-me-not by bumblebees. Also, the flowers that produce the most seeds are ones that never open fully and are thus self-pollinating.
Related species: the genus name, Impatiens, should be familiar to gardeners, as jewelweeds are in the same genus as the extremely popular landscaping flowers known by that name. The leaves are very similar, and the flowers also have a little "spur."
