Padrón Pepper in Zone 4a & 4b
Capsicum annuum
Yes, padrón pepper grows in zones 4a and 4b. Start seeds indoors Mar 20–Mar 27 and plant out May 29–Jun 5.
When to plant padrón pepper in zone 4b
Zones 4a and 4b 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.

|---|---|
| Direct sow / transplant outside | May 29–Jun 5 |
| Estimated harvest | Jul 28–Aug 4 (~60 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-3 ft.
Plant alongside it in zone 4b

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 4's season

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.
