Family: Sapindaceae

Lonomea is the endemic soapberry species that grows only on Kauaʻi and Oʻahu. It is related to the indigenous species, Sapindus saponaria also known as aʻe or mānele,  which is found on Hawaiʻi Island, Mexico, South America, Africa, and elsewhere in the the Pacific basin. This lonomea species does well when planted with other native plants like ʻaʻaliʻi shrubs, ferns, and groundcovers.

This tree can grow 30 to 50 feet tall and is an excellent xeric tree for drought-prone areas. Once established, water once a month only during driest months; over-watering may result in stem rot. The roundish or oval fruits resemble dates, and smell like figs or raisins, but are not edible. The flesh of the fruit creates suds like soap when mixed with water and can be used as such.

Trees are best grown from seeds after cleaning and scarifying. Seeds were also used by early Hawaiians for medicinal purposes and in seed lei. The wood was sometimes used for spears and other tools.
