Only the more vulnerable plants have been listed, you may have a plant that requires protection due to its current lack of health or other reason. This listing is provided for convenience only, and not a guaranteed comprehensive listing. Under typical mild frost conditions (predicted low between 27 and 34 degrees), these plants should be considered vulnerable to foliage or general damage. General damage is assumed when die-back, loss of following season blooming or death occurs. Legend explanations are below table. When in doubt “Cover it!”
