Life Cycle: Annual
Sowing: To break its dormancy this seed needs a period of cold moisture, a period of warm moisture, followed by another period of cold moisture. Mix the seed with moist sand and store it in the refrigerator for 40-60 days, then move it to a 70-75 degrees F location for 40-60 days, followed by another 40-60 day period in the refrigerator before planting. To accomplish this naturally, simply plant the seed in late fall and wait until the second spring after planting for germination. In late fall or early spring, direct sow the treated seed on the surface of the soil. This seed needs light to germinate.
Stratification: Cold/Wet for 12 Weeks, then Warm/Wet for 12 Weeks – Repeat
Latin Name: Impatiens capensis
Germination Ease: Stratify 24 Weeks
Jewelweed can become prolific in shady moist areas. Also known as Touch-Me-Not as the seed capsules will burst when touched, flinging seed far and wide. Blooming generally begins sometime in June and typically will continue through August, lasting for around 2 months or until frost.
Jewel weed will have a short taproot.
Of course, you could try to simulate this on your own. I would suggest mixing seed with moist sand in a zip-lock bag and storing in the refrigerator for 2 months. Then, place the bag on a low-grade heat source for a couple months, or even just try to keep it at room temp. Afterwards, place it back into the refrigerator for several months more. Finally, plant it outside.
There are generally a single flower growing from the uppermost leaves, and orange in color. You often find the petals have dark orange specks/spots on them. Individual blooms are approximately 1″ long. The flowers resemble bugles and are shaped like a cone that curves at the tip. This curl/curve or spur is where the nectar is located. Thus, only long-tongue bees, hummingbirds and butterflies can reach the nectar.
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!
