Alas, I'm about to hang up my trowel!
Since I didn't witness the crime, I'm not sure who's to blame,
but I always suspect our plentiful deer - I'm not really sure.
#1 is the same plant I posted 2d ago - notably missing all it's blooms.
#2-4 are the remnants of the flowers - the petals neatly removed.
Deer have never bothered my peonies, so I'm surprised.
Also the removal of just the petals, leaving the rest of the flower structure puzzles me.
My deer have never been so neat. But I don't know what else could have caused it.
The leaves and other branches show no indication of munching.
And the nearby Molly the Witch and several other peonies weren't bothered in the least.
I'm both aggravated and mystified. Has anyone else had this happen?
A small solace is my paeonia obovata which is blooming nearby.
