USDA Hardiness Zone 10b covers Tropical / Hawaii, including cities like Fort Lauderdale, FL · Honolulu, HI · Key West, FL. The zone experiences minimum winter temperatures between 35 to 40°F, which determines which perennials and woody plants survive winter outdoors.
With a growing season of 365 days, Zone 10b gardeners can grow food year-round with virtually no frost threat. The key is aligning your planting schedule with the frost window.
Pro tip: Your exact ZIP code matters. Zone 10b spans a range of microclimates — elevation, urban heat islands, and proximity to water can shift your personal frost dates by 1–3 weeks. Cloche uses your ZIP to give you precise, location-specific recommendations.
