Plant Zone Map

The Plant Hardiness Zone Map was updated for the 2024 gardening season with the addition of thousands more local weather stations. Look at your growing zone or gardening zone to understand which plants can survive your area’s climate. Did your planting zone change?

What Are Planting Zones?

When choosing perennial plants for your garden, it’s important to select varieties that can thrive year-round in your area, especially in regions where extreme winter temperatures are normal. Planting zones generally define which plants can survive winter in your area, and zones are typically listed in plant growing guides for reference.

The most commonly referenced hardiness zone map is produced by the U.S. Department of Agriculture (USDA).

How to Use Your Planting Zone

Planting zones are most helpful to gardeners growing perennial plants since they live beyond just one growing season, regrowing each spring. Perennials need to be able to survive winter in your area, so it’s essential to know how cold it typically gets in your area and whether a particular plant is hardy enough to survive those temperatures.

Perennial flowers, shrubs, and trees grow best when planted in the appropriate zone. You’ll find that winter damage occurs most often when plants are out of their range or comfort zone. When you choose plants for a garden or landscape, avoid selecting plants that are only marginally hardy for your region; that’s when you’ll see winter damage, poor growth, and a reduction in flowering.

Planting native species is a surefire way to achieve a stable garden.

For annual plants, like most vegetables and some flowers, it’s far more important to pay attention to things like the length of your growing season and the typical dates of your first and last frosts. Because annuals are only meant to last the length of one growing season, planting zones don’t necessarily factor into the equation.
