Sometimes I think USDA hardiness zones are like the twilight zone. Unless you experiment, you might never know if something will really work where you live, because everyone who supposedly knows, says it won't. I call that the hardiness zone of "Who woulda thunk it?"

Dumb name, I know. But, who would have thought that this very tropical Calathea ornata would freeze to the ground in a hard 20F freeze, and then...COME BACK? In zone 8B? BTW these leaves are emerging at a size of about 10" long. Not teensy tiny.
