Viola sororia, our common blue violet, is blooming in several spots in my garden now. Children always seem drawn to these; they’re the ones we decorate our sand pies with in nursery school. The white variation, sometimes called Confederate violet, has a special two-tone appeal. I’ve tried to relocate a few to my garden from a large empty lot near me, but they always disappear. Do they actually die (violets tend to be tough), or do they just revert to purple the next year? I’m not sure how that works. But violets are always welcome, whatever the color. They’re a favorite (useful, edible, cheery) spring bloom.
