Pepper varieties in the C. baccatum species have white or cream colored flowers, and typically have a green or gold corolla. The flowers are either insect or self-pollinated. The fruit pods of the baccatum species have been cultivated into a wide variety of shapes and sizes, unlike other capsicum species, which tend to have a characteristic shape. The pods typically hang down, unlike a Capsicum frutescens plant, and can have a citrus or fruity flavor.
The C. baccatum species, particularly the Ají amarillo chili, has its origins in ancient Peru and across the Andean region of South America.It is typically associated with Peruvian cuisine, and is considered part of its condiment trinity together with red onion and cilantro. Ají amarillo literally means yellow chili; however, the yellow color appears when cooked, as the mature pods are bright orange.
