Hardy kiwi (Actinidia argute) need a long growing season (about 150 frost-free days) and when fully dormant, and they have been acclimated to cold slowly, plants can withstand temperatures to about -25 degrees F. Publications listed here provide an overview of hardy kiwi production in the Pacific Northwest.
