I live in the Savannah area and I have seen a Bismarckia and some of the best looking CIDP down in Saint Simons/ Brunswick area. I believe the Brunswick Library has 60ft CIDP
In my travels throughout the Southeast, I always thought that the healthiest Sabal Palmettos I've ever seen anywhere were in the Georgia coastal plain and sea islands. They just get so dense and green. Might be both a climate issue and a soil nutrient issue. Palmettos are scrawnier looking in Florida until you get into the Orlando area, then they seem to spruce up again.
