I'm 6a in Va. And my linare does ok. here. unless it is a really bad winter then it dies back but regrows from root system in spring. My fig tree does the same thing. No longer a tree Its a bush now with a dozen separate stems. But i'm only about 70 miles from the largest "Hot Air" furnace in the world. Known as Washington DC Which might be the reason why.
we got about 4" of snow and ice today. will see what it looks like after that melts off.
