One of my granddaughter Stasia's favorite late-August activities is to find a patch of Jewelweed seed pods and demonstrate just how it got the common name of "touch-me-not." Impatiens capensis, which is also known as the camp counselor's best friend, on account of the plant's ability to help blunt the untoward effects of contact with Poison Ivy, has the rare talent of throwing, explosively throwing, its small seeds, sometimes five feet or more, and any kid observing the show will want to make it happen again and again. The Jewelweeds weren't quite ready to do their hurling, but it turns out that other members of the Impatiens clan, including the garden varieties we have growing in various pots, have the same talent, so, after I demonstrated with a ripe pod, Stasia was quickly searching the garden flowers for fat, ripe pods. One quick squeeze and there were soon seeds flying everywhere. The plants didn't need to hope for the passage of an explosion-triggering bird or beast... they had us. We did their seed-launching bidding.
