Hi Nas.I have the same 6 zone and i tried many inground varieties in 4 years of trials,like hardy chicago,sal's,alma,excel,red sicilian,nordland,marseille vs black,violleta bayernfeige,salem dark,english brown turkey,paradiso,san peitro and celeste belleclaire.If you dont cover them,even with a light protection,they all die to ground.The only one who survive to me a second winter is a dark fig,from Greece,Chios island,named by me...BLACK GREEK.I left half of tree Uncovered in winter after i pruned the long green branches late in fall.We had,here in Cleveland,Ohio -3fahrenheit for few days and a single digit for a whole week.It's geen,alive.That's what i'm calling a Hardy fig tree! Sometime,names and fame dont matter! Marius
