Answer: Both cultivars of rosemary will survive the winters in your area. 'Arp' is said to be the hardiest of the rosemarys, but 'Salem' is touted to be hardy as far north as Salem, Massachusetts. Both plants can survive a short period of time in the temperatures that are normal for your area. If it freezes down to the soil, the roots should remain alive and send up new shoots in the spring.
