Hardiness Zones Explained

Gardening Terms Explained

New to gardening? Terms like planting zone, USDA zone, and hardiness zone might sound confusing—but don’t worry! It’s simpler than it seems, and we’re here to help.

The USDA divides the U.S. into 13 zones based on climate data, helping gardeners choose plants that can survive winter in their area. (Note: This applies mainly to perennials—plants that return yearly—not annuals, which last just one season.)

Why Temperature Matters
For perennials to thrive year after year, pick plants suited to your zone’s coldest temps. Zones range from cold (low numbers, like Minnesota’s 3–4) to warm (high numbers, like Florida’s 9–10). Terms like growing zone or USDA zone all mean the same thing.

Beyond Zones
While zones are helpful, nature isn’t always predictable. You might succeed with a plant outside your zone—or see a recommended one struggle due to factors like snow, humidity, or elevation. Still, knowing your zone gives you the best shot at a thriving garden!
