Thanks, Horseshoe!
I'm in central Mississippi -- Zone maps place us in 7b or 8a. My property is a little colder since we are away from town and up on a hill where there is more wind. Our lot drops quite a bit from side to side (and front to back), The lower area gets much cooler faster in the evenings and we often have fog. My guess is I'd need to consider planting the trees in the high area (where they would be suscitible to the wind) but not the lower ground (which is wet longer and where the fog settles). However, the area is wide open and even the low ground receives the morning and all day sun. If they need any break from the very hot sun, I do have the option of planting at the back of the lot (north) which is bordered by woods (or even on the east side of the house which eventually gets afternoon shade and where we already have some Magnolias and an Oak that are big enough to give some shade -- but there is also plenty of room to plant on that side and stay away from the other trees, too).
