Growing Scotch Bonnet Peppers: A Complete Profile
By Growing Home Greens Team · September 30, 2026
Scotch bonnet is the squat, hat-shaped hot pepper of Caribbean cooking. Baker Creek says the name comes from its resemblance to a tam o’shanter, and that it is essential to Jamaican escovitch. It is Capsicum chinense, like habanero.
Heat and harvest
Bonnie Plants rates its Yellow Scotch Bonnet at 100,000 to 350,000 Scoville units. Bonnie lists 80 to 90 days after planting and Baker Creek 90 to 100 days. Baker Creek notes the thick walls hold up to long cooking in jerks and curries.
Start early and support the branches
Baker Creek recommends starting seed indoors 8 to 12 weeks before your last frost because of the long season; we schedule it at ten. It also recommends stakes or cages, since branches get heavy with fruit.
Bonnie gives a plant height of 24 to 36 inches. One plant per square foot in the Garden Designer. The Bell Pepper profile covers shared care, and the companion guide lists neighbors.
Growing it next to other peppers
Different pepper varieties cross-pollinate easily, hot ones included. NC State Extension notes that when hot and sweet peppers cross, the heat shows up in later generations grown from saved seed, and suggests keeping varieties 20 to 30 feet apart if you plan to save your own. Baker Creek, which grows seed for sale, isolates varieties by at least 500 feet. If you buy fresh seed each year, you can plant sweet and hot peppers side by side.

Good companions for Scotch bonnet pepper
- 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.
