Jewelweed in the Garden: Pretty, Possibly Useful

Lee Reich is an expert on gardening who writes about the subject for the Associated Press. Recently, he wrote a story about a plant that a gardening friend could not identify -- even though the plant is common.

The plant has green leaves and large, yellow flowers. It appeared in Reich's friend's garden although he had not planted it. The area did not get a lot of sunlight.

Reich identified the growth as soon as he saw it --- jewelweed.

His friend was surprised. He thought he knew what jewelweed looked like. In fact, he had an area in his garden filled with the plants. But those were bright orange.

It turns out that jewelweed comes in a lot of colors. Orange is most common in the United States. But jewelweed flowers can be yellow, pink and even brown.

The fruit of the jewelweed explodes at the lightest touch. Seeds fly out in all directions. That quality is why "touch-me-not" became the common name for jewelweed.

Scientifically, the plants are known as impatiens. Impatiens capensis is the name of the orange touch-me-not. The jewelweed with the yellow flowers is Impatiens pallida. And there are a thousand other kinds of jewelweed. All are famous for their ability to produce bright, colorful flowers even when growing in shade. The flowers appeal to bees, hummingbirds and other pollinators.

Reich says jewelweed's "impatient" method of seed spread might be a good quality if you want a plant that spreads and returns every year. Of course, a plant that is too good at that could take over more space than you expect or want it to.

Anything with ‘weed' in its name might seem like a bad addition to your garden, Reich notes. But he says some jewelweed versions are pretty enough to have been offered by dealers in native plants.

Jewelweed is not just another pretty flower, however. The U.S. Forest Service website notes that the plant has a long history in Native American medicine. Jewelweed sap, or fluid, can be used directly on the body to ease pain and itching from many conditions, including poison ivy rash. The sap has also been shown to have antifungal properties and can be used to treat athlete's foot.
