Authentic Jamaican Scotch Bonnet Pepper(red Strain) Not Regular Habanero 50 Seed 90 days. Among the hottest peppers anywhere, Habanero reaches up to 215,000 Scovilles of heat! These little peppers look harmless, but use them very sparingly, and remember to wear gloves when handling them to avoid transferring that heat to your eye! Blocky, wrinklked peppers measure about 2 inches long and slightly less wide, maturing from silvery-green to bright orange on the plant. Start seeds indoors or, in climate with short growing seasons, outdoors at least one week after last frost. If starting indoors, allow 7 to 10 weeks for the seeds to mature into seedlings large enough to transplant safely. Fertilize when the blooms appear, and water well. Fruit is most nutritious if allowed to ripen on the plant.
