I should add, I treat my gardens every year with grub killer, because there are grubs in the yard.
The leaves are all really nice. I was surprised to see it in the flower. I have been reading up on borers and some of the literature says they will eat the flowers on their journey to the rhizome, but this guy is large for the season. Do they grow fast? We have had spells of really warm weather and he could have started early.
Also, I never saw any eggs on the leaves and I have been fussing in the gardens for weeks now.
