Barry, Cayce, SC. I have a plant that I left outside in a pot under a magnolia grandifolia and it suffered no damage what so ever.
My zone is 8a/b but this winter was milder with no temps below 23 Deg F. As the caudex is underground I plan to plant it in the ground this spring.

I am presently overwintering in the garage. However, I have seen a 5 ft tree of c. debaoensis happily growing in somebody's garden in my town. She's had her plant for years. I intend to plant mine in a rather shady area, not too wet or dry. Since it was pricey, I will baby it for a while.

UPDATE July 2015. It has survived two years inground. Partial sun location with amended clay soil. Access to sprinkler head. Slow growing but so far so good.

This plant will definitely grow in colder than 10a. I have three here in zone 9a under a light canopy and they are doing well. They were defoliated this past winter at 22 degrees (unusually cold) but came back strong this year with bigger leaves than ever, and because the caudex is underground it could almost be grown like a perennial (try in zone 8b?). I have had some problems with yellowing on one of my three plants though.

One of the coveted 'split leaf' Cycas species, this one from China. It basically has underground stems and long leaves, up to 12', shooting out of the ground. THe leaves are usually bipinnate and look similar to Cycas micholitzia, only much more profuse on the rachis. It is a highly ornamental cycad and my hopes are one day I will discover it CAN grow in my climate.. but not sure yet. Some populations are from relatively high altitudes and have a northern range that would approximate maybe what we have here in So California. Worth a try.
