I didn't even notice the flower when I passed by this plant the first half-dozen times I passed it, the day this picture was taken. Once I did notice it, though, I became kind of intrigued. It's an unusual color for a flower (the color in the picture is fairly accurate), and since the only Dianthus I was familiar with before this were the bright white, searing red, and glow-in-the-dark pink of the annual type we sell, this was even more of a revelation.
I don't know if I'd want one in my yard. (I'm not sure I want a yard, either, as far as that goes.) But it's oddly compelling all the same.
