Sapindus drummondii (Western Soapberry)

Sapindus drummondii, commonly known as Western Soapberry, is a tall deciduous tree native to the central and southern United States. It is characterized by its pinnately compound leaves and large clusters of yellowish-white flowers that appear in mid-summer, followed by small green fruits that turn yellow when ripe. The fruit contains saponin, a natural soap-like substance that can be used for cleaning purposes.
