Your USDA Plant Hardiness Zone tells you which perennials are likely to survive winter where you live.
How to use it
- Look up your zone by ZIP code on the USDA Plant Hardiness Zone Map
- Check plant labels for the zones they're hardy in
- Zones are about winter cold, not summer heat or rainfall
- Learn your average last spring frost and first fall frost dates too
