Hardiness Zones

Hardiness is a complex thing and can vary from one climate to another. We try hard to represent appropriate zones but please note that these may not fit exactly with your garden. Factors such as nighttime heat, sudden temperature swings and depth of snow cover can be harmful or helpful to a plant thriving in your landscape for many years. The map below is based on recently compiled data. More information, including a zip code zone search can be found HERE.
