Capsicum frutescens is a wild chili pepper having genetic proximity to the cultivated pepper Capsicum chinense native to Central and South America.[2] Pepper cultivarsofC. frutescens can be annual or short-lived perennial plants. Flowers are white with a greenish white or greenish yellow corolla, and are either insect- or self-pollinated. The plants' berries typically grow erect; ellipsoid-conical to lanceoloid shaped. They are usually very small and pungent, growing 10–20 millimetres (0.39–0.79 in) long and 3–7 millimetres (0.12–0.28 in) in diameter.[3] Fruit typically grows a pale yellow and matures to a bright red, but can also be other colors. C. frutescens has a smaller variety of shapes compared to other Capsicum species. C. frutescens has been bred to produce ornamental strains because of its large quantities of erect peppers growing in colorful ripening patterns.[2]

The Capsicum frutescens species likely originated in South or Central America. It spread quickly throughout the tropical and subtropical regions in this area and still grows wild today.[8]Capsicum frutescens is native to Central America and Northern and Western South America. C. frutescens may be related to C. chinense.[9]
According to Richard Pankhurst, C. frutescens (known as barbaré) was so important to the national cuisine of Ethiopia, at least as early as the 19th century, "that it was cultivated extensively in the warmer areas wherever the soil was suitable."[10] Although it was grown in every province, barbaré was especially extensive in Yejju, "which supplied much of Showa as well as other neighbouring provinces". He singles out the upper Golima River valley as almost entirely devoted to cultivating this plant, where thousands of acres were devoted to the plant and it was harvested year-round.[11]
Siling labuyo, the local cultivar of C. frutescens in the Philippines, developed from plants introduced during the Spanish colonial era. The fruits are widely used for making traditional dips (sawsawan), spiced vinegar (like sinamak), and condiments like palapa. They are also commonly added to various dishes. The leaves are also eaten as a leafy vegetable, most notably in the soup dish tinola.[13][14][15][16]
