Answer: The cold and freezes that we experienced in January 2007 were unusually severe. Generally, most of our desert-adapted plants will come through winters okay. Cat's claw vine tolerates both cold (15 degrees F) and tremendous sun and heat although some folks don't like that because it clings to surfaces with its "cat's claws" it can do damage to paint and stucco over time. However, on a trellis that isn't much of a concern. Other cold-hardy evergreen vines with flowers include: lilac vine (15-20 degrees); primrose jasmine (15 degrees) and Lady Bank's rose (10 degrees; thornless).
