USDA hardiness zone
Zone 11b
Rolled up from the 16 ZIP codes in our data that are classified zone 11b, covering 0 nurseries and garden centers across 0 cities we track in this zone.
Average minimum winter temperature
45°F
Frost
Frost is rare or absent across most of this zone; timing here follows temperature, not a spring/fall frost date. Any single ZIP's own exact frost status is on that ZIP's own lookup page, not approximated here.
Crops by frost hardiness
What grows here, and when
Frost is rare or absent here, so cool-season (hardy/semi-hardy) crops typically go in during the cooler months and warm-season (tender/very-tender) crops before the hottest months arrive, rather than on a frost-relative schedule.
Planting windows and crop timing here are computed from USDA/NOAA climate data and the university extension sources cited below, not a site visit or soil test. Treat this as a starting point: local conditions vary, and a local nursery or extension office can advise on your exact site. See our full Disclaimer.

Zone 11b means an average annual extreme minimum winter temperature of 45°F to 50°F on the 2023 USDA Plant Hardiness Zone Map (USDA/ARS with the PRISM Climate Group at Oregon State University, 1991-2020 records). Every ZIP here carries its zone matched by centroid against the map, not by its polygon boundary, via phzmapi.org's ZIP-level derivation.
None of zone 11b's 16 own ZIPs has a matched NOAA frost station or a growing-season figure in our data, so we hold no frost date and no season length to report for this zone at all. That is an absent data field, not a rare-frost finding.
We track zero nurseries with a ZIP in zone 11b. The ZIPs here sit in Puerto Rico and the Florida Keys; a local extension office is a better source than this page until we close that data gap.
