Instead, though, I think I'll just post their portraits.
Here's the yellow Canada violet. It's native to woodlands. This is, I think, my best violet photograph.
Here's the regular purple violet that everyone knows and loves.
The most populous violet in our yard is the white violet shown below. I tried to capture it's essence in the photograph, but it didn't turn out right - the focus is poor on the top two petals. Oh well. You can still sort of see the beautiful purple lines and yellow center, which a casual observer can only see when getting right up close and personal with the plant. (The little purple flower in the background is a creeping charlie flower.)
