This plant is cold hardier than the range indicates here. A plant has survived two winters in zone 8b in Savannah, Georgia at Armstrong Atlantic State University. Based on its success, I acquired two seedlings to grow in Jacksonville, Florida, zone 9a.

This tropical oak has the largest of all acorns. The photo was taken near Huatusco, Vera Cruz, Mexico -- the north end of the species' range. The acorn came from a large tree about 1 meter in diameter and 30 meters tall.
