This spring my clump of Dusky Challenger looked suddenly like something had made a bed of it overnight. All the leaves were mashed down, one fan entirely broken off. Next to that, something had nipped off part of the monkshood, and spat it out. And next to that some daylily leaves had also been nipped off and spat out. I suspect deer did it. Or maybe a groundhog. But I think that deer more often sample things and spit them out. We also have some feral cats that laze around in that area, but obviously they aren't herbivores. I am wondering if a fawn or deer bedded down there overnight and also sampled the plants.
