The Russian Olive is a native of southern Europe, and western and central Asia. It was introduced into North America during early colonial times. The trunk typically is crooked. The thin bark is brown, fissured, and it shreds off in long strips. This is a hardy and vigorous tree and it grows easily in many kinds of soils. Its tolerance of salt makes this a very useful tree along mid-western highways where de-icing salt damages many trees. Landscapers like the Russian Olive for its unusual combination of gray foliage, silver-white flowers, and silver-scaled fruit, which eventually turn reddish.
