This beautiful native wildflower came up on its own in several of my perennial beds this year. I pulled some of them out, but let a few others stay, to see what they would do, and I'm so glad that I did! The plant produces small but beautiful bright yellow flowers, and attractive seedpods. It is also a host plant for the banded sphinx moth (Eumorpha fasciatus), so I now have several very colorful, large, red-green-black-&-white caterpillars on the plants. I've collected seeds to give to friends now!
