My 15 year old peony did not come back this spring. I left all the foliage on all winter. What happened? Is there anything in the root system that I can salvage?
I am sorry to hear about your plant. I am not sure what could of happened, unless it simply got too cold for the plant to survive winter. Perhaps, its age was a factor as well.
