The USDA published an updated zone map a year or so ago. We went from 6b to 6a, which I’ve taken as license to be a bit more adventurous with what I leave in the ground.
We have a bed of cana lilies that still haven’t been killed by this year’s freeze. They usually die/get cut back to ground level and enough of them make it through the winter for the bed to reestablish.
This year I’m trying my luck with two globe artichokes.
