Noteworthy Characteristics

Sapindus drummondii, commonly called western soapberry, is a small to medium-sized deciduous tree with an open-rounded crown. It grows to 20-50' tall and features glossy compound medium green leaves, grape like yellow-orange fruits (ornamentally attractive but toxic if ingested), deep yellow fall foliage color, and gray bark divided into scaly plates. It is native to the southwestern U.S. and northern Mexico (Missouri to Kansas and Oklahoma south to Louisiana, Texas, New Mexico, Arizona and Mexico). In Missouri, it is found on limestone and dolomite glades, bluff bases and along streams in several counties in the far southwestern corner of the State (Steyermark). Yellowish-white flowers bloom in late spring (May-June) in large open panicles to 10" long. Flowers are followed by yellow-orange grape like fruits (usually one-seeded) that mature in September-October. Fruits eventually turn black with persistence on the tree well into winter. Although toxic and inedible, the fruits (contain saponin) produce a soapy lather when mashed. Native Americans made soap from the fruit. Pinnate compound leaves (each to 15" long) with 8-18 untoothed, lanceolate, medium green leaflets (each to 2-3" long) turn excellent yellow-gold in autumn. Scaly trunk and often persistent fruit provide winter interest.

Synonymous with and sometimes designated as Sapindus saponaria var. drummondii.

Genus name comes from the Latin words sapo meaning soap and indus meaning Indian in reference to the use of these sapoinin-rich fruits in the West Indies to produce a soapy lather used as a soap.

Specific epithet honors Scottish botanist and naturalist Thomas Drummond (1790-1835) who collected this plant in the 1830s.


No serious insect or disease problems. Powdery mildew, leaf blight and leaf spot may appear in some areas.
