I'm sorry I have been MIA as I've been out of town dealing with a family emergency. Things are stable now, and I'm back at home.
, Judy and Bob for your responses. Judy we are in the zone; I'm about 2 1/2 hrs away and only a few degrees warmer. I checked my other planted echies, and see that they are pretty much staying green depending on the extent of frost/freeze damage. They are located in a sunny area. So, they are not completely dormant. Therefore, I think I'll either plant these or sink the pots in the ground now and mulch with straw or shredded oak leaves. Then I'll divide them in spring.
