Granadilla

A granadilla is any of several species of plants of the genus "Passiflora", including:
#the giant granadilla, also known as "badea" ("Passiflora quadrangularis")
#the sweet granadilla, known in Spanish simply as "granadilla" ("Passiflora ligularis")
#the granadilla (South African English for "passion fruit", "Passiflora edulis")

The granadilla is a sub tropical (not tropical) so can be found growing where it’s warm (it likes temperatures of 15-18º C) and damp (between 60 to 100cm of water a year in rainfall). You’ll find it in the mountains of the Andes, Africa and Australia. It also grows in Argentina, Brazil, Colombia, Ecuador, Hawaii, Kenya, Mexico, South Africa and Venezuela.

The name "granadilla" is derived from the Spanish-language noun "granadilla", which was originally the diminutive of "granada" (pomegranate/"Punica granatum"), the name of another plant with similar fruits and similar tasting seeds that is not closely related to granadillas. The granada, in turn, was called so because of the grains/seeds of its fruits.

It is thus also a Spanish place-name:
