These violets aren’t strictly local, because while they’re in my yard, they were a gift last April from Wesley Whiteside, gardener extraordinaire from my hometown of Charleston, Illinois. I complimented him on how many varieties of violets he had blooming, and he offered to give me samples. I told him that was very kind but I was flying back. He said not to worry, they would be fine in a plastic bag for awhile. Soon I was amazing the security people at the little Champaign airport with my nine varieties of carry-on violets.
Right now, only the deep purple one is open. (Native.)
Common Blue Violet (Viola sororia)
