Thanks everyone. These little jewels of varied color are most welcome any time of the gardening year. They are easy to grow and care for. They almost are a natural wild flower self-propagating themselves by seeds. A word of caution, they can be a bit invasive where not wanted. Violas form small colonies and are quite inviting in gardening arrangements. Individual gardeners will be the final judge. I vote "thumbs up" for them!
