One of the most sought after ornamental peppers, the Black Prince is a unique pepper because of its black foliage as well as its red and black peppers. Black Prince pepper plants have beautiful purple flowers that eventually turn into peppers that start off black and ripen to red. Although Black Prince peppers are known for their strikingly beautiful appearance, they actually have a medium heat level as they average 5,000 to 30,000 Scoville Heat Units (SHU). The cone-like peppers are smaller than the Black Pearl pepper, which are round like a pearl. The heat level of the Black Prince pepper is similar to the Pequin pepper, Tabasco pepper, and Black Cobra pepper. A beautiful addition to any garden, the Black Prince pepper is a very popular choice for ornamental pepper growers.
