About This Collection
USDA Zone 11 is the warmest hardiness zone in the continental US and Hawaii, with minimum winter temperatures above 40°F. This zone covers Hawaii and the very southernmost tip of Florida. In Zone 11, frost is essentially unknown — the limiting factor for plant survival is heat and humidity, not cold.
Zone 11 gardeners can grow true tropical plants that would be impossible anywhere else in the US: heliconia, gingers, tree ferns, tropical orchids, and an extraordinary range of flowering shrubs and trees. Many plants sold as houseplants in colder zones grow as landscape plants in Zone 11.
PlantWise's Zone 11 filter shows plants rated to survive your climate. Because Zone 11 data is less common in mainstream plant databases, we include Zone 10 plants that also thrive in Zone 11 conditions.

What plants are exclusive to Zone 11?
True Zone 11 exclusives include heliconia, tree ferns, tropical gingers, and many Hawaiian native plants. However, most Zone 10 plants also thrive in Zone 11, giving you a vast palette to work with.
Can I grow tropical fruit trees in Zone 11?
Yes — Zone 11 is ideal for mango, papaya, breadfruit, starfruit, rambutan, and lychee. Citrus, avocado, and banana also thrive. Zone 11 is one of the few places in the US where you can grow a true tropical fruit orchard.
