Silver Buffaloberry (Shepherdia argentea) is an upright, deciduous shrub with thorny gray stems and gray-green leaves. Silver Buffaloberry is dioecious, with male and female flowers on separate plants. Small greenish-yellow flowers appear in spring and are followed by small red berries on the female plants. These berries are edible and sour and can be eaten off the bush, used in jams or jellies, or left on the shrub for the birds. Both male and female plants will be necessary to produce the berries. Since this shrub is suckering, thorny, and difficult to prune, it can be used as a specimen plant, but is more commonly used as a background, hedge, windbreak, or privacy planting. It is tolerant of urban pollution.
