Native to South America, this plant produces long, thin, dark red fruits that are extremely spicy. Cayenne plants prefer a limited, even water supply, good drainage, full sun, and a long, hot summer. Start seeds indoors 40-50 days prior to the last frost, and thin seedlings to at least two inches apart in the flat. Transplant out to garden after the soil has really warmed up. These plants prefer compost that is higher in phosphorous than nitrogen, and kelp is well-tolerated, making for spectacular yields.
