Actually, I just remembered! I'm pretty sue the eaten ones are Japanese Beetles. I caught on crunching on one the other day. But it could be mites in addition.
I have found most perennials do better planted in the fall down here. When I first moved I lost a lot of plants because I planted them in the spring so now I plant them in the fall. I think I will try spring again, but earlier. That may have been prt of the problem.
