The distribution of giant granadilla spans across several continents, thriving as a cultivated species and also an introduced one in various tropical and subtropical regions. In its native range, giant granadilla can be found throughout parts of South and Central America. Beyond its native territory, giant granadilla has been introduced to parts of Asia, Africa, the Pacific Islands, and the Caribbean. Although giant granadilla is generally cultivated for its ornamental and fruit-producing qualities, in certain areas, such as Australasia and some Pacific regions, giant granadilla is sometimes thought to be potentially competing with local flora and may have an impact on ecosystems.
