Savius

Savius is a genus of trees in the family Sapindaceae, commonly known as soapberries or lychees. The genus is native to the Americas, with species found from the southern United States to Argentina. Savius trees are typically small to medium-sized, with compound leaves and small, often fragrant flowers. The fruit is a drupe, usually round or oval, and can be edible or inedible depending on the species.

One of the most well-known species is Savius saponaria, also known as soapberry. This tree is native to the southeastern United States and produces berries that contain saponins, which are natural foaming agents. Historically, these berries were used for cleaning clothes and hair. Savius saponaria is also a popular ornamental tree due to its attractive foliage and clusters of berries.

Other species of Savius have various uses. Some have medicinal properties, while others are cultivated for their fruit, though these are less common than the commercially cultivated lychee and rambutan, which belong to the same family but different genera. The genus Savius is an important part of the biodiversity of its native regions, providing habitat and food for local wildlife. Conservation efforts are in place for some species that are threatened or endangered due to habitat loss.
