Soursop is the fruit of Annona muricata, a broadleaf, flowering, evergreen tree native to Mexico, Cuba, Central America, the Caribbean, and northern South America, primarily Colombia, Brazil, Peru, Ecuador, and Venezuela. Soursop is also produced in some parts of Africa, Southeast Asia and the Pacific. It is in the same genus as the chirimoya and the same family as the pawpaw.
The soursop is adapted to areas of high humidity and relatively warm winters; temperatures below 5 °C (41 °F) will cause damage to leaves and small branches, and temperatures below 3 °C (37 °F) can be fatal. The fruit becomes dry and is no longer good for concentrate.
