Updating prior review:
I tried an experiment with this peony, and overwintered it in a 5 gallon bucket in my unheated garage, as my ground was too hard to plant. (Boy, there's a run-on sentence...) :D
Watered weekly, no other special care. By March, stems had emerged. Late May this beauty bloomed! Spectacular fluffy bloom of pink and cream. Not much scent, but thrilled she is evidently such a vigorous grower!
