Description
Sapindaceae is commonly referred to as the “soapberry family” and includes trees, shrubs, and lianas. Serjania is the largest genus of the Sapindaceae, which includes 215 species. Species in this family are largely found in Asia and America, specifically in tropical to subtropical regions. 

In Florida, the Sapindaceae has14 representative native species  within 8 distinct genera, including maples (fig. 1), buckeyes or horse-chestnuts (fig. 2), and soapberries (fig. 3).

Fun facts
Sapindus saponaria can be used as soap. (This explains the common name for the family, “soapberry”). By crushing the berries to get to the saponin, Native Americans and early settlers were able to make soap and other cleansers.
Schleichera trijuga produces macassar oil, which can be used in ointments.
Paullinia cupana produces guarana, a potable liquid. Brazilians are known to be very fond of drinking guarana! It can also be found in Rockstar and Redbull energy drinks.
Blighia sapida contains an edible aril which can be poisonous if eaten during the wrong stage of ripeness! People of West Africa are known to eat this fruit.
Melicocca bijuga is harvested for its tasty Spanish lime in South America.

Does anyone know where I might find a full grown Western Soap Berry tree in South Florida?

Hi Rhonda,
Western soapberry (Sapindus saponaria var. drummondii) is not a plant that is common to Florida - it is found in the southwestern U.S. and Mexico. Wingleaf soapberry (Sapindus saponaria var saponaria) or Florida soapberry (Sapindus marginatus) are its closest Florida relatives.
