USDA Zone 10aRiverview, Florida frost dates, USDA zone, and a full-year planting calendar, drawn from the nearest NOAA station and tuned to the local season.

These dates come from a station roughly 16 km away, the closest with full normals; terrain around Riverview (elevation, water, pavement) can move your real frost dates a few days either way. Zone 10a is warm enough that Riverview can grow subtropical perennials, and the short (or absent) frost period barely limits the annual calendar.
