Touch-Me-Not Family

Yellow Touch-Me-Not (Impatiens pallida). Also known as Pale Touch-Me-Not or Jewelweed. The name “Touch-Me-Not” comes from the explosive seedpods, which give no end of entertainment to children and any adults who are not beyond being entertained by natural amusements. The pods have parallel ribs connected by a thin membrane, and the membrane gets thinner and weaker as the pod ripens. At length the membrane can be ruptured by the slightest touch, and then the ribs instantly coil into springs, sending seeds flying in all directions.

Orange Touch-Me-Not (Impatiens capensis). Also known as Spotted Touch-Me-Not. Very similar to the Yellow or Pale Touch-Me Not (I. pallida), and often found in the same colony. Most of the differences are subtle; I. capensis tends to have smaller, darker leaves, often with a noticeable bluish tinge. The flowers, however, leave no doubt about the species: the bright orange of I. capensis is instantly obvious
