Capsicum frutescens is a species of chilli pepper that is sometimes considered to be part of the species Capsicum annuum. Pepper cultivars of Capsicum frutescens can be annual or short-lived perennial plants.
The 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 to 10–20 millimetres long and 3–7 millimetres in diameter. The fruit typically grows a pale yellow and matures to a bright red, but can also be other colours.
Capsicum frutescens has a smaller variety of shapes compared to other Capsicum species, likely because of the lack of human selection.
