When to plant in Jupiter, FL

USDA Zone 10b

Jupiter, Florida frost dates, USDA zone, and a full-year planting calendar, drawn from the nearest NOAA station and tuned to the local season.

Jupiter's growing season is short at roughly -10 days, so succession planting is limited; lean on transplants over direct sowing for anything slow to mature. Zone 10b is warm enough that Jupiter can grow subtropical perennials, and the short (or absent) frost period barely limits the annual calendar.
