germinating jewel weed seeds

Jewelweed plants grow higher when they are located in clusters, so if seeds are sown close together, the plants can help support each other and develop taller stems. If you’d like to keep your jewelweed plants on the shorter side, be sure to space the seeds farther apart.

Thanks to the touch-me-not bearing pods full of seeds that explode at even the slightest contact, this plant can easily disperse seeds that readily germinate in the right conditions. This means you could end up with an abundance of jewelweeds in your garden without even trying.


The natural habitats of this plant are moist areas, such as woodland edges and marshes, so they will naturally require more frequent watering. The jewelweed will wither if the soil becomes too dry for a prolonged amount of time.

Tthe jewelweed plant is very vulnerable to frost at any stage of its growth, and it will die when exposed to extremely cold temperatures.

The jewelweed is considered an easy plant to grow and will require little hands-on care once it’s established, providing it’s planted in an area where the soil remains moist. Better yet, the dense growth of these plants can actually help discourage the development of weeds.

If you have the proper growing conditions, Jewelweed will not require care. It is a native plant that will not require special fertilizers.

There are a few obvious uses for Jewelweed – namely that of a rain garden, shade garden, or along a pond/stream. It will do well in disturbed areas too.

Pretty much. Well, what happens is the capsule will form and then dry out. As it dries out, the walls (which are really valves holding water) of the capsules will build tension. Eventually the tension is released and the seeds are launched. Wellesley College did some research and calculated that seeds should be able to travel over 1.5 m from the plant!

Growing Conditions

The leaves on Jewelweed are alternate along the stalk, and anywhere from 2-5″ long (5-12 cm) by 1/2 as wide. They are ovate, almost spade shaped. The edges are scalloped or serrated with large teeth.

Seed capsules will eventually form in the fall. These capsules are oblong and when opened, split apart throwing seed. This allows Jewelweed to make colonies in proper growing conditions, as the seed dispersal is quite efficient.

Hummingbirds, bumblebees, and butterflies will visit the flowers. Several different moth caterpillars eat the foliage.

Seeds from Jewelweed are eaten by a variety of birds and mammals. Quali, Pheasants, Grouse, and field mice will all eat the seeds. Deer do browse the foliage as well.
