Briefly explain plant hardiness zones and one common misconception about it.

# Plant Hardiness Zones **Plant hardiness zones** are geographical regions defined by average annual minimum winter temperatures. The USDA system divides North America into zones (1-13), with each zone representing a 10°F difference. These zones help gardeners select plants likely to survive winter in their area. ## Common Misconception **Misconception:** *Hardiness zones tell you whether a plant will thrive in your garden.* **Reality:** Hardiness zones **only** indicate cold tolerance—specifically, whether a plant can survive your lowest winter temperatures. They don't account for: - Summer heat and humidity - Rainfall patterns - Soil type - Growing season length - Microclimates A plant rated for your zone might still fail due to excessive summer heat, poor drainage, or other factors beyond winter cold. Successful gardening requires considering multiple environmental factors, not just the hardiness zone.
