It looks like East Tennessee is a zone 7 https://www.gardeningknowhow.com/planting-zones/ Gardenias are rated for USDA planting zones 8-11. Since you are on the fringe/outskirts of the planting zone I would say that if you took extra steps to winterize your gardenia during cold snaps (by covering with a blanket or cardboard box) then you should be able to make this work.
