Got a brochure from Hartman's Nursery in Michigan today. They advertise the Chicago Hardy fig as super hardy. "it will freeze back to the ground....come back and make fruit". It is apparently the only fig they sell. Darn, it should be a real winner here in OK. I have three of them; two pots and one in the ground under a barrel. I should get a fig or three this summer. We'll see.
