Padrón Pepper in Zone 9a & 9b
Capsicum annuum
Yes, padrón pepper grows in zones 9a and 9b. Start seeds indoors Dec 21–Dec 28 and plant out Mar 1–Mar 8.
When to plant padrón pepper in zone 9b
Zones 9a and 9b share the same average frost dates, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. It needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Dec 21–Dec 28 |
|---|---|
| Direct sow / transplant outside | Mar 1–Mar 8 |
| Estimated harvest | Apr 30–May 7 (~60 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-3 ft.
Before you plant: Zone 9b summers commonly stall padrón pepper's fruit set midseason. See the details below.

Padrón peppers come from Galicia in northwest Spain, where Baker Creek notes they are sautéed in olive oil, salted and served in tapas bars. The well-known catch is that most are mild and an unpredictable few are hot.
How padrón pepper fits zone 9's season
Zone 9b's frost-free window runs about 293 days, from February 15 to December 5. Padrón pepper needs about 60 days from transplant to first harvest.
Heat warning for zone 9b: Zone 9b summer nights commonly exceed 75°F, which stalls pollination and causes blossom drop in Padrón Pepper 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.
