Comfrey in Winter

Signs of life! Bocking 14 from a divided root, started last spring.

Walked the field last weekend. The field has been covered with snow for a bit, but some areas are opening up.
The nighttime temps are in the teens (F) at night, and last week were in the singles. Not sure how long this green leaf will last uncovered. Either the temps or the deer.
Plenty of green clover is hugging the dirt as well.
Just think, the roots are doing the same thing.

Location?
Maybe add it next to your elevation?
