I love how resilient comfrey is, we split root cuttings into solo cups last summer, they grew in the cups and we never decided where to plant the 7 new plants before fall took hold. We didn’t know whether they would make it sitting outside all winter in a plastic cup, a real mild one for Michigan this year, but we still had almost a solid week of subzero windchills. Yesterday I looked at them chilling in one of our beds and two already have new chutes #comfrey #gardening #michigan
