Here, in zone 7, if we leave them outside we call them "dead" before spring. Usually I bring in the two potted ones I grow and always kept them in a cool window (northeast exposure) and they always died a sudden death on 3/19. This year I put them both in a very sunny window and they both survived and thrived.
A neighbor keeps her Tuscan outside and it's dead as can be. She also failed with Arp.
I tend not to prune any herbs outside until new growth commences.
