I'm not sure if they are all native to my area, but my property borders a moist marshy area which is also wooded. There are bright yellow. white with a blue blush and of course violet flowered varieties. The white with a blue blush and the yellows tend to be taller and lesser in numbers. They seem to be more prevalent in the sunnier areas. Their early blooms are very welcome, no matter what their color. They are shallow rooted and my soil is very sandy , so it is not difficult to pull or move them if they are not in a desired area.
