Capsicum chacoense is a species of the genus Capsicum native to South America. While it is rarely cultivated by humans, it, like all Capsicums, is edible.
Capsicum chacoense plants are compact perennial (annual in cooler climates) shrubs that grow close to the ground and grow approximately 80 cm and up to 1 metre in height and width. The flowers appear in summer and are small, white flowers with five petals. The fruit, with a roundish/triangular shape, grows to be around 2.5 cm long, 0.5 cm wide when fully ripe, and it matures from green to either yellow or bright red in colour. Plants tend to crop heavily each season and in warm areas can easily keep producing for four or five years. The plant's leaves are large, flat, and roundish, with a point at the end. The plant branches evenly, forming a small to medium shrub in most cases.
The plant is known locally as 'Tova' or 'Covincho' in Paraguay, and as 'ají putaparió' in Argentina. The latter is a euphemism related to its heat, often causing people to swear when eating it.
C. chacoense is native to Argentina, Bolivia, and Paraguay, and for the most part is only known to occur in its native region.
This chilli species is sometimes cultivated for food,.
