USDA Hardiness Zone 11A is effectively frost-free, covering Hawaii, the Florida Keys, and Puerto Rico, with average annual minimum temperatures between 40ยฐF and 45ยฐF. The growing season spans 364 days โ frost is absent in all but the most exceptional years. Zone 11A gardeners can grow tropical and subtropical crops year-round, but the absence of a cold season means some temperate vegetables (garlic, onions, many brassicas) lack the vernalization period they require. Choosing tropically adapted varieties and managing intense heat and rainfall are the primary challenges. For a personalized forecast based on your specific zip code, use our free planting calendar.
