A prolific cayenne-type heirloom pepper popular in Southeast Asia, producing curved 4-6 inch fruits with sweet-spicy flavor and medium-hot heat around 20,000-50,000 SHU. Ripens from green to bright red and excels for drying, sauces, and fresh use.

The Goat Horn Pepper is a classic cayenne-style Capsicum annuum cultivar known for its distinctive curved pods that resemble a goat's horn. Fruits average 4-6 inches long with medium-thick walls, smooth glossy skin, and a tapered shape; they mature from dark green to vibrant red. Heat registers 20,000-50,000 Scoville units with an initial sweet, fruity note that builds into a lingering spicy finish. Plants grow 2-3 feet tall, are highly productive, and bear over a long season in most climates. Originally accessioned as PI 321003 and noted as a Spanish variety (also called Sweet Spanish Long), it became especially popular in China, Thailand, and Southeast Asia for both culinary and ornamental use. Excellent for drying into powder, making hot sauces, pickling, stir-fries, or fresh eating.
