Apart from its poetic uses the fruit is important culturally in Brazil where a reference to it suggests something as being unique to Brazil on the assumption that Brazil is the only place where jabuticaba grows. It is also native to Bolivia, Paraguay, Argentina, Uruguay and Peru and was introduced in to California, USA at the beginning of the 20th century.
