I received a tuber from a family Fern leaf Peony bush last summer. I planted it in a pot and in March some of the leaf branches were starting to come up. We got a cold snap and it hasn't grown or flowered any more. The plant is starting to turn brown at the base like my other ones usually do at the end of the season. I have other Peony plants around my yard that have grown and bloomed already. This plant has been in our family for generations and I hate to think I killed mine.
