When to plant in Boca Raton, FL

USDA Zone 11a

Everything below — frost dates, hardiness zone, and what to plant when in Boca Raton, Florida — is derived from the closest NOAA station with complete climate normals.

Boca Raton's growing season is short at roughly -5 days, so succession planting is limited; lean on transplants over direct sowing for anything slow to mature. These dates come from a station roughly 18 km away, the closest with full normals; terrain around Boca Raton (elevation, water, pavement) can move your real frost dates a few days either way. Zone 11a is warm enough that Boca Raton can grow subtropical perennials, and the short (or absent) frost period barely limits the annual calendar.
