Is there a USDA Frost Free Zone 12 in California?

Recommended Posts

Seeking a frost free zone 12 in California.

There must be a well protected area hiding on the side of a hill facing south thats protected from cold winds and exposed to fohn type winter winds and sunshine. Not too humid or wet even in winter.

There are a few locations that are noted as zone 11, but none that I know of that are zone 12.

Likewise. I’m guessing La Jolla, Coronado, or Avalon are probably the closest but they’re still some form of zone 11.

Malibu is a solid zone 10b.

Zone 12 would be fully tropical, and will be much further south in Baja California

Agree w/Jim.. this zone, -at least currently-, doesn't exist anywhere in U.S. CA. Have to go to the far southern end of Baja Sur ( La Paz, Cabo Pulmo, Cabo San Lucas, ) Even there, i'm somewhat on the fence about referring to the climate as a " Puerto Rico ( or similar )- like zone 12 " since there is often strong influence from the mild.. but still cooler, compared to the Caribbean/Atlantic, Pacific. Todo Santos, while at a " tropical " latitude, is often milder compared to La Paz or Cabo due to where it is located, even though the distance between it and La Paz is relatively short.

Very dry as well, even during their "rainy" season compared to islands in the Caribbean/ zone 12 regions of Mexico and Central America.

While there are zone 11 areas in California, plenty of stuff one could grow to perfection in other zone 11 areas that would often struggle or flat out refuse to grow in CA's version of the same zone.  If, in the future, areas of the state did warm enough to be considered zone 12, you'd likely see similar issues, even if you could still grow more things..

The day dream of a steamy, wet and lushly tropical zone 12, or 13.. in California?.. Maybe in 9-20 Thousand years, at the absolute minimum, if we stay Ice Cap free and the wet tropics expand considerably toward the poles. Imagine  San Diego's current climate would likely be somewhere near Anchorage, Alaska in that case.
