Plant Hardiness

When choosing plants for your garden, it is crucial to consider their hardiness. Hardiness refers to a plant's ability to withstand cold weather, drought, and other environmental stressors.

The United States Department of Agriculture (USDA) Hardiness Zone Map is one of the most widely used tools for classifying plant hardiness. The map divides the contiguous United States and Canada into 11 hardiness zones based on average minimum winter temperatures. The first USDA hardiness zone map was published in 1960 and has since been updated several times. The most recent version of the map was released in 2012. While the hardiness zone map is a valuable tool for gardeners, it is essential to remember that it is only an estimation. Local conditions, such as wind and sun exposure, can cause significant variations in plant hardiness within a single zone.

By selecting well-suited plants for your climate, you can help ensure they will thrive in your garden. While some plants are more resistant to environmental stressors than others, all plants can be adversely affected by extreme conditions. When choosing plants, consult a trusted source (such as a nursery or gardening center) for information on the plant's hardiness zone, ensuring the best chance of a plant surviving in your area.
