Growing Orchids Outdoors in southern Mississippi

[drtd]

I am moving from Portland, OR to southern Mississippi, and was curious which orchids would be suited for growing outdoors either year round, or seasonally. Portland is USDA zone 8b, although lately due to the change in climate, I would categorize it closer to Zone 9a. According to the USDA zone maps, southern Mississippi is Zone 8a, only slightly colder (on average) compared to Portland. I have had fairly good success growing most things outdoors from late spring, well into fall, although the humidity levels get pretty low during the summer months. Any input/experience would be helpful.

Thanks!
