Russian olive

(a.k.a. silverberry, oleaster, wild olive, Persian olive)

Green fruits at the end of a twig with lanceolate leaves

Russian olive is a shrub or small tree, usually 12 to 45 feet tall. It can grow up to six feet per year. It forms a dense, rounded crown. Near the ground, its branches spread from 10 to 20 feet. Unpruned trees have five or six main stems starting near the ground. The twigs are flexible, coated with a gray, scaly pubescence, and have a thorn at the end. Bark is reddish-brown and thin, with shallow fissures. It exfoliates into long strips.

Russian olive is commonly found growing along floodplains, riverbanks, stream courses, marshes, and irrigation ditches at elevations from 4,500 to 6,000 feet. It is tolerant of considerable amounts of salinity or alkalinity, and can survive considerable droughts. In addition to reproducing from seed, it sprouts from the root crown and sends up suckers. It thrives under a wide range of soil textures, from sand to heavy clay, and withstands flooding and silting. It grows best in deep sandy or loamy soils with only slight salt and alkali content.

Russian olive has no forage value for livestock or big game, although both browse the foliage at times. In general, Russian olive-dominated communities provide inferior wildlife habitat to that of native riparian vegetation. Russian olive rapidly colonizes lowland fields, often chokes irrigation ditches, and damages tires and equipment. Once established, Russian olive is difficult to control and nearly impossible to eradicate. The most effective combination of control efforts is cutting trees, followed by either spraying or burning the stumps..
