Most of the cultivated fuchsias are of South American origin, and some of 

 the South American ones are grown in Mexican gardens, where they are 

 known as " arete," "Adelaida," " flor de arete," " aretillo," " fusia," or " flusia." 

 The fruits are edible, and those of F. splendens are said to be used in 

 Guatemala for preserves. Some of the species are reported to have tonic, 

 astringent, and febrifuge properties.
