Orange Jewelweed (Impatiens capensis)

This plant started sprouting up all over the yard last month, especially along the creek. I figured it must be some kind of weed, but the hummingbirds like it, so it's a good weed. Restoration Place, another blogger who's doing the 100 Species Challenge, had it in her list. So, now that I know what it is, I can list it as one of my 100 species!

I'm up to seven:
1. Poison ivy
2. Virginia creeper
3. Wild blackberry
4. Lamb's Ear
5. Great laurel
6. Fireworks Goldenrod
7. Orange Jewelweed
