UPDATE! I know what it is and where it is. It is Masterwort (Astrantia), it is in the Rose Garden at Woodland Park in Seattle, and it is not a vine. All courtesy of the kind people at Dave's Garden. I am going to add their link in the sidebar if they are not there already.
Original post:I shot this photo in the Seattle Botanical Gardens, or was it the Rose Garden? Or are they one and the same? It was near the zoo and it was a beautiful place, but I could not find an ID tag for this plant.
I've posted it to the Plant and Tree Identification forum on Dave's Garden, but am posting it here as well in case one of you knows what it is.
Unfortunately, I can't remember if it was a climber or a shrub. Darn.
