What Is a Hardiness Zone?

The USDA Plant Hardiness Zone Map divides the United States into 13 zones based on the average annual extreme minimum winter temperature. Each zone represents a 10°F range, and zones are further divided into “a” (colder half) and “b” (warmer half) sub-zones.

Knowing your zone helps you choose plants that can survive your winters. A plant labeled “hardy to Zone 6” can tolerate winter lows down to -10°F. If you're in Zone 7 or higher, that plant will do fine. If you're in Zone 5, it may need winter protection or be grown as an annual.

How to Use Your Zone

Choose the Right Plants

Select plants rated for your zone or lower. A plant hardy to Zone 5 will thrive in Zones 5 through 11.

Plan for Protection

Plants at the edge of your zone may need mulch, covers, or sheltered placement to survive harsh winters.

Consider Microclimates

South-facing walls, urban heat islands, and elevation all create local conditions that may differ from your zone.

Plants by J & Your Zone

We grow and ship from the Southeast US (Zone 7b–8a). Our berry plants are hardy to Zones 3–9, making them suitable for most of the country. Tropical plants like dragon fruit, papaya, and passion fruit require Zone 9+ outdoors but can be grown in containers and brought indoors in colder zones. Every product page lists the recommended hardiness zones.
