Encyclopedia Article for oleaster

small deciduous tree of Eurasia, about 4.5 to 6 m (15 to 20 feet) high. It has smooth, dark brown branches that often bear spines and narrow, light green leaves that are silvery on the undersides from a covering of minute scales. The flowers are small, greenish, fragrant, and silvery-scaled on the outside, as are the edible, olive-shaped, yellowish fruits, which are sweet but mealy. The oleaster is hardy, wind resistant, tolerant of poor, dry sites, and thus useful in windbreak hedges, but it is also widely used in ornamental hedges.
