Soapberry is a single-stemmed, low-branched, round-crowned tree, growing 10-50 ft. tall, depending on habitat. Gray, sculpted bark is distinctive in the dormant season. Leaves up to 18 inches long with a central axis and as many as 24 paired leaflets, usually fewer, and often no terminal leaflet. Leaflets unsymmetric with the broader part of the blade toward the leaf tip and the base rounded on the broader side and tapering on the narrower side. Leaflet tip elongate. Flowers in large, cream colored clusters up to 10 inches long and 6 inches wide, appearing in May and early June. Fruit fleshy, globose, about 1/2 inch wide, flesh translucent, yellow turning darker with age, sometimes persistent on the tree until the next flowering season.
The poisonous fruit, containing the alkaloid saponin, has been used as a soap substitute for washing clothes. Necklaces and buttons are made from the round dark brown seeds, and baskets are made from the wood, which splits easily.
The variety name of this plant is named for Thomas Drummond, (ca. 1790-1835), naturalist, born in Scotland, around 1790. In 1830 he made a trip to America to collect specimens from the western and southern United States. In March, 1833, he arrived at Velasco, Texas to begin his collecting work in that area. He spent twenty-one months working the area between Galveston Island and the Edwards Plateau, especially along the Brazos, Colorado, and Guadalupe rivers. His collections were the first made in Texas that were extensively distributed among the museums and scientific institutions of the world. He collected 750 species of plants and 150 specimens of birds. Drummond had hoped to make a complete botanical survey of Texas, but he died in Havana, Cuba, in 1835, while making a collecting tour of that island.
