Peanuts are the strangest thing in most vegetable gardens. They flower above ground, self-pollinate, and then the fertilised flower sends a stalk called a peg downward, which pushes into the soil and forms the pod underground. Nothing else in the bed does this, and it explains most of what peanuts need from you.
How peanut fits zone 11's season
Zone 11b is frost-free, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
