Q.What Is Eating My Actaea Simplex? Planted Last Year When In Flower.
Something has eaten right through every flower stem … will it grow more flower stems? It looked beautiful last year .. bought & planted when in flower. I really want to support the butterflies & reclaim my plant from whatever is eating it.

My research says black cohosh pests include cutworms and blister beetles. Here's some info.
