What Grows in the Florida Keys

USDA Zones 10b

The Florida Keys spans USDA hardiness zone 10b — a zone band wide enough that plant choice, not possibility, is the interesting question.

A frost-free coral archipelago of thin alkaline soils where tropical fruit and container gardens replace conventional ground beds. Expect mango, tomato, orange, and sweet potato to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
