Cumin is a warm-season seed spice that needs a long, warm growing season to mature its seed, unlike most quick-turnaround culinary herbs.
How cumin 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.

Zone 2 sows before zone 3 here, which looks wrong and is not. USDA zones rank winter cold, not season length, and zone 2 is mostly interior Alaska, where hard winters come with warm summers. More on what a zone measures.
