What Does Zone 8B Mean?

USDA Hardiness Zone 8B means your area's average annual extreme minimum winter temperature falls between 15°F to 20°F (-9°C to -7°C). This is the coldest temperature you can typically expect in a normal winter, based on 30 years of climate data.

Your zone primarily determines which perennial plants (trees, shrubs, perennial flowers, and fruit bushes) can survive outdoors year-round. It's also strongly correlated with your frost dates, which are the foundation for calculating when to plant annual vegetables and flowers. Learn more about what hardiness zones mean.

Frequently Asked Questions

Plan for a midsummer slowdown. Many crops (tomatoes, peppers, beans) stop setting fruit when nighttime temperatures stay above 75°F. Use shade cloth (30-50%) over sensitive crops during the hottest weeks. Focus summer plantings on heat-lovers: okra, sweet potatoes, Southern peas, and eggplant. Your second opportunity comes in fall — plant cool-season crops in August and September for harvest through winter.

Two full growing seasons. Your 240-270 frost-free days support warm-season crops from spring through early summer, then again from late summer through fall. Cool-season crops grow through your mild winter. With planning, you harvest something fresh from the garden every month of the year. Few zones in the country offer that kind of year-round productivity.
