Lost all of the leaves on it during the winter when its greenhouse got down to 35F, but I saw no damage to the roots or stem. It is just now starting to put out new shoots and leaves. Next winter it will go into the inner greenhouse where it stays warmer.
Thankful I didn't lose it, but it is very slow growing. The greenhouse it is in has seen bright light and temperatures from 60F(night) to 100F(day) for months now, so I don't know why it took so long to grow again.
