I checked yesterday and the darmera is throwing out new sprouts, so it is on the road to recovery. I cleared out around it and will also mark it with either a ribboned stick or maybe a chicken wire cage. This particular neighbor isn't really a menace, he's pretty occasional about any sort of maintenance. He's also quite sensitive and I don't want to make him feel badly so will just leave it. Sometimes a little venting is all that is needed.
