Gardening 2014: Tragedy #1

I've been watching the progress of my east perennial bed with great amusement this year. I am easily entertained by plants. I'm still waiting to see what plants ended as victims to our freakishly cold winter.*

Yesterday, I saw from a distance that the columbine looked like it had bloomed. I gleefully skipped over to look more closely and saw this:

Something's eaten over half the plant.

Gardening is not for the faint of heart.

*Because I have limited knowledge about plants, there's also always a chance I'm carefully weeding around and composting an actual weed that I think is a flower. There are at least 2 plants currently in this plant/weed limbo.
