Superhot peppers (Ghost, Reaper, Scorpion, and their relatives) are a different commitment than a standard pepper plant. Days to maturity commonly runs 120-150+ days versus roughly 75-100 for a regular hot pepper, and germination itself is slower and far less consistent, sometimes taking 2-6 weeks instead of the usual week or so. Start these far earlier than you'd think to.

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.
