Hardiness zone is one guide to indicate a plant’s ability to withstand an average minimum temperature. However, other factors, including soil type, moisture, drainage, humidity and exposure to sun and wind can have a direct effect on the success of a plant’s survival. The number guides throughout our catalog indicate the range of hardiness for a particular variety. Use this as a guide, but keep the other factors in mind when deciding where and what to plant.
