Shepherdia argentea aka Buffalo Berry

Shepherdia argentea, also known as silver buffaloberry, bull berry, or thorny buffaloberry, is a species of Shepherdia in the Oleaster family. It is native to central and western North America, ranging from the Prairie Provinces of Canada (Alberta, Saskatchewan, Manitoba) to Ventura County in California, as well as northern Arizona and northwestern New Mexico. This upright, bushy deciduous shrub resembles a tree and has oblong leaves covered in silvery scales. In early spring, it produces insignificant greenish-yellow flowers, followed by bright red berries on female plants. The plant is noted for its attractive silver-scaled branches and leaves, and its fruit matures in the fall. It typically grows up to 12 feet tall and wide, but can reach heights of up to 18 feet. Shepherdia argentea thrives in various habitats, including riparian areas, woodlands, foothills, plains, and canyons. It was first collected by Meriwether Lewis in 1804 in northeastern Nebraska. The stems of this plant are silver-scaled, and its leaves are opposite, elliptic, and densely-pubescent with silvery scales. The plant produces small, yellowish tubular flowers with a 4-lobed calyx in spring, and if pollinated, female plants bear spherical, pea-sized, bright red fruits either singly or in clusters.
