Pale Touch-me-not, Impatiens pallida A few more passing comments about these native impatiens. Their name is derived by their explosive seed capsules- Touch-me-not. When fully ripe, the 1/2 inch long mini banana-looking fruits peel themselves under pressure. Ka-pow! The seed goes blasting out in all directions, and you are left with a curly green husk in hand. The yellow species tend to grow a bit taller than the orange one, some form stands in ditches well up to 5 feet in stature- perhaps even more. And interestingly enough, both species seem to like similar conditions: damp ditches or road-sides, stream banks and generally low light. However, they rarely seem to grow side-by-side. Any one care to comment on this?
Our native impatiens, Jewelweed or Touch-me-not is rarely utilized in formal gardens, although it is just as lovely as the colorful imported impatiens of lesser stature. These members of the Balsam family have distinctive irregular blossoms held aloft on 1-2 foot stems. Impatiens capensis is orange, Impatiens pallida pale yellow, both sport similar trumpet-shaped flowers which quickly becomes an attractant for Ruby-throated Hummingbirds. 
This plant is a "natural" for free ranging among the Hosta. Yes, we ex-landscape gardeners won't give up our Hosta any sooner than we would give up our children (however if you had asked while the kids were still in their teens- I might have considered...)

This Hosta is a stout fellow of 3.5 feet or so, and holds his own against any wildflower encroachment, however native Impatiens are easy to manage in the garden beds and can be readily thinned if they become too crowded. Try seeding some native impatiens to attract wildlife in your home flowerbeds, and enjoy the flutter-by-products of the natural-looking, healthy Ohio native plants.
