Solanum quitoense, commonly known as Naranjilla, is a tropical perennial herb native to Central America and South America, where it thrives in the understory of mountain forests and in clearings. It is characterized by large, elongated heart- or oval-shaped leaves that can reach up to 45 cm in length, and both the leaves and stems are covered in short purple hairs, which can cause skin irritation. The plant typically grows to about 1.5 to 2.5 meters in height and width. Naranjilla’s flowers are small and white, leading to the production of round, orange fruits about 4-6 cm in diameter. The fruits have a citrus flavor, often described as a combination of rhubarb and lime, and are notable for their culinary uses. The juice is green and is popular in beverages such as lulada.

Naranjilla is valued for its unique fruit flavor and ornamental foliage, making it an interesting addition to tropical and subtropical gardens. It is often used in culinary applications, especially in the preparation of fresh juices and drinks. While the plant is said to grow best in partial shade, it requires protection from strong winds and direct sunlight, which can scorch the leaves. It prefers consistently moist, well-drained soils rich in organic matter. Gardeners should be cautious when handling the plant due to the irritating hairs. Naranjilla can be susceptible to root rot if overwatered and may attract pests such as whiteflies and aphids.CC BY-SA 4.0
