Christmas Peppers Christmas peppers are very prolific, beautiful, compact plants producing upright 1 1/4 inches long by Â½ inch wide peppers in white, yellow, orange, red and purple. All five colors often appear on the plant at the same time. The Christmas pepper is typically grown as an ornamental plant, but its fruit does have a mild flavor with a bit of bite when eaten fresh. Hot Banana Peppers Hot banana peppersâ€”also called Hungarian hot wax peppersâ€”are productive, stocky, ever-bearing, colorful plants. Although they prefer heat, they will grow well in cool climates either in the garden or in a container. Growing no more than 18 inches tall, banana pepper plants produce upright, banana-shaped, 4-6 inches long chili peppers that are fully mature in 70-75 days. As banana peppers mature their flavor develops, with the fully mature red peppers having more tang than the immature green ones. These are tasty peppers for stuffing. 'Inferno' is a very productive variety: it produces uniform fruit, and is excellent for pickling.
