Each month name links to the national page for that month.

Frost dates in zone 11b
Frost dates, not the zone number, set the sowing windows above. These are the regional frost windows from our frost table, with the ZIP code records for a few places in each region. ZIP code figures come from the nearest weather station in the NOAA 1991 to 2020 Climate Normals at the 50 percent level, so in one year out of two the last frost comes later. Check your own ZIP code in the Frost Lookup.

What zone 11b is good for
Any perennial, shrub or fruit tree rated to zone 11b or lower should survive a normal winter where you are. That is the question a zone answers well. For fruit trees there is a second number that matters just as much: winter chill hours, which decide whether a variety will set fruit at all. The free app checks both.
