yes, looks cool!
Only about 15F, it can get down to -15F so all i can say it didn't have a problem with 15F.
All my borderline plants, blueberries, blackberries all survived this year. Harvest is going to be good. Some damage to blueberries from being in the garage and growing out too soon, oh well. Next year I'll try something else. All my figs did really well in the garage, currants and gooseberries in pots too. I should have a very nice harvest of all kinds of fruits this year. Why if I get nothing from Nadia, I'll still be happy. Plenty of peaches, nectarines, and pluots too. Lot's of first time fruits too, I can't wait! I have a number of new plants to baby too. Black currants, elderberries etc.
