It is known by a number of common names, including common meadow violet, purple violet, the lesbian flower, woolly blue violet, hooded violet, and wood violet. It is the state flower of Illinois, Rhode Island, New Jersey, and Wisconsin. Self-seeding freely, in lawns and gardens it can become a weed.
