I'm not a fan of palm trees myself; I much prefer mixed evergreen/deciduous hardwood forests. Still, palm trees are interesting since they have no dormant period and they have an unusual growth pattern.

The sabal palm and its cultivars -- particularly the dwarf varieties tend to be the hardiest species among the palms. I frequently saw them growing in yards around Memphis when I lived in the area and they seemed to winter over just fine. The house we rented had a large sabal palm in the front yard and we had record cold one year but it seemed to do okay outside of one or two frost-burned fronds that we had to remove the following spring.

South Carolina has several varieties of native palms which are hardy; when I was there I saw dwarf palmetto plants growing all over the place in the wetter areas.

Yes, there have definitely been changes in the climate.

Check out this little animation which shows how USDA hardiness zones have shifted north from 1990-2006:

My hometown shifted from zone 4a to zone 5b and my current city shifted from 4b to 5b. If this keeps up in 20 years I will have silly palm trees in my front yard :: Oh well, I will be retired by then (hopefully) and can always move to the Arctic Circle!

I get that, but I prefer a variety of evergreens: palms, conifers and other. It makes me sad to watch deciduous trees go dormant, and the scenery it creates is very dull.
