Tradescantia, tradescantia zebrina. Also known as wandering jew or cucaracha.
This ornamental plant is one I have growing all over the yard. It's also one of three on display at the museum.
It's a plant you can't get rid of, not that I want to. It's known for stopping hemorrhages, among other things. Bill is a bleeder so the next time he gets a cut I'll be bringing him leaves and putting it to the test.
