What zone 10a means for Orlando
Hardiness zones are based on the average of the coldest night of each winter over 30 years (1991 to 2020). In zone 10a, that average is 30 to 35°F (-1 to 2°C). Plants labeled hardy to zone 10a or colder should survive a typical Orlando winter. A plant rated only to a warmer zone will need a sheltered spot, a pot you can bring inside, or treating as an annual.

Choosing plants for zone 10a
When you shop, look for the hardiness range on the tag or in the catalog, such as "zones 4 to 9". Pick perennials, shrubs and trees whose range includes 10a. If you are set on a plant rated only to a warmer zone, plant it in a sheltered spot against a south-facing wall, mulch the roots before winter, or grow it in a container you can move into a garage. Zones only cover winter cold, so also check sun, water and soil needs. More in how to read a plant tag.
