Anaheim is the long, mild green chile that gets roasted, peeled and stuffed or chopped into green chile stew. It is part of the same New Mexican chile group sold as Big Jim, NuMex and, when grown in New Mexico's Hatch Valley, Hatch chile. Hatch is a growing region, not a variety.
How Anaheim pepper (New Mexico, Hatch) 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.
Heat warning for zone 11b: Zone 11b summer nights commonly exceed 75°F, which stalls pollination and causes blossom drop in Anaheim Pepper (New Mexico, Hatch) at the height of summer (University of Maryland Extension, via UDel Cooperative Extension). Expect a slow patch for fruit set during the hottest stretch even though the plant keeps growing. It typically resumes once nights cool.

Good companions
- Basil: Reputed to repel aphids and improve pepper growth nearby, but a controlled garden trial testing this same claim on a related crop found no pest-reduction benefit from basil, and found higher pest counts on the basil-companioned plants. Treat this pairing as unproven, not as a working pest deterrent.
- Onion: Reputed to deter many common pepper pests, though this specific pairing hasn't been tested the way onion/carrot pest-masking has. Treat it as garden tradition. (usually zones 3-10, so not a pairing for zone 11b)
