Unknown Soldier

I try to avoid posting flower images because they are pretty easy for most people. Why shoot something that anyone else can too?

But I couldn't resist posting this. This little specimen of blossoms is about 2 inches long at most. It's also a rare example where I was happy with the picture as-shot. All I did was crop it and tweak the contrast to make the colors pop a little more. I have no clue what this plant is.
