This native wildflower can be found growing in moist areas near streams or ditches. The tiny orange flowers are unmistakable in their unique shape, and the watery flesh of the stems will combat poison ivy.
Should you find yourself far from sink and soaps and in direct contact with poison ivy or poison oak, you can ward off that nasty itchy rash by finding this plant. Break off a good portion of it and use it like a green scrubby "soap" wherever you came into contact with the poison ivy oils.
You'll want to wash again with a good anti-ivy soap when you get back to civilization, but in the meantime this plant will stave off the rash.
