Sapindus saponaria, commonly known as Wingleaf Soapberry, is a deciduous tree or shrub native to a variety of habitats including open woodlands, riparian zones, and scrublands in the Southwestern US, Mexico, Central America, and the northern parts of South America. It typically grows to about 20 feet (6.1 meters) in height but can reach up to 50 feet (15.2 meters) when grown in isolation. The Wingleaf Soapberry is characterized by its alternate, pinnately compound leaves that are thick, leathery, and glossy green, turning yellow in the fall. Its small, fragrant white flowers bloom in dense terminal panicles measuring 6 to 10 inches (15 to 25 centimeters) long, with var. drummondii flowering in May–June and var. saponaria in November. The flowers are followed by translucent yellow to golden-brown berries that contain saponins, which can be used as a natural soap.

The Wingleaf Soapberry is valued for its drought tolerance and adaptability to different soil types, making it suitable for xeriscaping and as an ornamental tree in arid regions. It is also used for shade and as a street tree in urban landscapes. This species prefers full sun but can tolerate part shade and requires low to medium amounts of water, thriving in soils with a range of drainage capabilities. While it is generally low-maintenance, gardeners should be aware that the berries can be messy and that the tree may self-seed, potentially becoming weedy. Additionally, the saponins in the berries are toxic if ingested.CC BY-SA 4.0
