Yellow Wood Violet (Viola glabella)

Roses are red,
Violets are blue... except when they're yellow, like the one above. Up until recently I always thought violets were violet colored, a sort of bluish purple. The variety pictured above, however, was recently encountered in Goldstream Park and is a common native wildflower known as the Yellow Wood Violet, Stream Violet or Smooth Violet (Viola glabella).
