So... last November, I adopted a pitiful little lump of dirt and twigs from a local nursery's bargain bin. No labels but I popped it in the ground (a few days before we got a half foot of snow). It is now blooming its little heart out... but I still have no clue what it is. Does anyone recognize this clematis? The colors are fairly accurate-- it's sort of a purply pink with petals that are darker on the edges and lighter toward the center.
