plant id

[Schwefelfell]

I'm in southern Ontario, and I'm seeing this one everywhere, although nobody around here seems to know what it is. The flower, purple/blue just looks like a little bead poking out from between two leaves, so it's hard to describe for flower identification guides. Alternating leaves, smooth stem, less than a foot tall. Any ideas?

[artemiss]

I can't find the name for it anywhere either, but it waws all over where I grew up in central illinois..I will keep looking, as I KNOW I saw it for sale in a plant catalog this year...
