heuchera in containers for winter
Can I keep my huechera in its container for winter or should I plant it in the ground NOW?
Heuchera in zone 5 or warmer should survive over winter when left in pots, though the container would still need to be wrapped to protect the roots. That said, you can also plant these in spring or fall, so it would be fine to go ahead and put the plant in the ground now before it gets too cold to do so. You can add a layer of mulch to help insulate the newly planted Heuchera as well.
