Susan for you in zone 7 they will most likely stay evergreen. In the spring cut off the sadder looking leaves and new growth will come in. Best color is early spring and late fall. You can usually divide during the third spring.
Sheryl Northern Beauty is a hybrid of Christmas Rose which flower before the Lenten Rose. November is a little early but in the right zones Christmas Rose flowers around Christmas and Lenten Rose around Easter. By me my Lenten Roses flower late April to early May just before most of my spring bulbs come up.
