Q: This flower is too pretty to relegate to an unseen portion of my yard where it is. Any advice that I can have on it would assist me a lot.
A: You have a butterfly pea, Clitoria mariana. It is perennial from Iowa through Florida, usually sprouting at the edge of cleared areas. It likes dry woodland soil, in broken sunlight during the day.
You can propagate it by collecting the seed and planting them nearby.
