Hhmm, let's see...

The Wikipedia
disambiguation page lists 27 possibilities for which "Viola" the reader might want to know about. Two
different musical instruments are on top of the list; the plant genus is #4.
And a messy genus it is.
Viola contains "violets", "pansies", and "violas". Mostly they like moist areas, but there's one that grows in the local desert!
* (That's the
"Sagebrush violet",
Viola trinervata, named for its unusual leaf shape.) Certain
Viola species are the larval food plants of
Speyeria and
Boloria butterflies (the Fritillaries), and sure enough, there's a desert species,
Speyeria coronis, that exploits
trinervata. Everything's connected to everything.
People seem to distinguish the violets, pansies, and violas primarily by leaf shape, flower size, presence of stems, and so on. But the butterflies seem to distinguish only by chemistry, and don't care one whit about that other stuff. Most of the Speyeria that ordinarily feed on meadow violet will also happily chow down on decorative winter-blooming pansies. But give them a different violet that looks perfectly reasonable to a human, and they're like as not to turn up their noses, get poisoned, or starve to death.
Yeah, I know, more than you ever thought to ask. But hey, at least I didn't bore you with the story about how the distant ancestor of this viola came home with me in 3rd grade as a present from my teacher. Some present -- it's been taking over my Mom's gardens ever since, and now mine too! Tough little critters. Pretty, too. Good teacher.
Glad you enjoyed the photo, folks. Thanks for dropping by!
