Zone 11
Frost-free places such as the Florida Keys. Few temperate plants succeed; the palette is tropical.
What zone 11 means
Zone 11 covers places where the average coldest night of the year falls between 40 and 50 °F (4 to 10 °C). Zone 11a is the colder half (40 to 45 °F) and zone 11b the warmer half (45 to 50 °F).
A plant rated “hardy to zone 11” is expected to survive that typical winter low with its roots in the ground.
What the zone doesn’t tell you
- Summer heat and humidity — many plants rated for zone 11 still fail from heat, especially in the Southeast.
- Rainfall and drainage — cold plus wet soil kills plants that would survive cold in dry soil.
- Frost dates — the length of the growing season is a separate question; check local frost dates.
- Your microclimate — walls, slopes, pavement and wind shift conditions by half a zone or more across one property.
Find your exact zone on the USDA Plant Hardiness Zone Map, then treat it as one filter among several. The planner’s OL-HARDY check uses the zone you set for the site.

Hardiness is necessary, not sufficient: check light, moisture and soil on each plant page, and prefer plants native to your region. Filter the plant library by zone 11.
