  Trees of Wisconsin: Elaeagnus angustifolia, Russian olive   (Site not responding. Last check: 2007-10-07)
Elaeagnus angustifolia was first planted as an ornamental tree and for wildlife cover and sometimes escapes.
Elaeagnus umbellata is similar but the leaves tend to be a bit wider and the silvery scales on the leaves and twigs often have a few brown scales mixed in.
Also the fruit of Elaeagnus umbellata is a red juicy berry, as opposed to the silvery dry fruit of Russian olive shown above.

  Elaeagnus - Wikipedia, the free encyclopedia
Elaeagnus (Silverberry or Oleaster) is a genus of about 50-70 species of flowering plants in the Elaeagnaceae.
The fruit is a fleshy drupe containing a single seed; it is edible in many species, though generally lacking a good flavour.
Elaeagnus species are used as food plants by the larvae of some Lepidoptera species including The Gothic.

 Elaeagnus angustifolia - Wikipedia, the free encyclopedia
Elaeagnus angustifolia (Russian Silverberry, Oleaster, or Russian-olive) is a species of Elaeagnus, native to western and central Asia, from southern Russia and Kazakhstan to Turkey.

Elaeagnus umbellata is a shrub or small tree with alternate, petioled leaves in small lateral clusters on twigs of the current year.
Elaeagnus umbellata is native to China, Korea and Japan and was introduced to the United States for cultivation in 1830 (Rehder 1940).
Elaeagnus umbellata seems to be a problem only in locations where small stands or rows were planted, usually within the last 10-20 years, and have begun to spread into adjacent fields or natural areas.

 Invasives Plant Pests Literature Collection: Elaeagnus umbellata   (Site not responding. Last check: 2007-10-07)
Abstract: The distribution of Myrica cerifera-, Elaeagnus umbellata-, and Alnus glutinosa-infective Frankia (MciF, EuiF, and AgiF) was determined in soils from five locations in central Illinois using a plant infection dilution technique.
N mineralization rates were measured repeatedly over a one year period using in situ incubations of soil cores in oxygen-permeable polyethylene bags at 0-10 and 10-20 cm soil depths, and also by burying mixed-bed ion-exchange resin in soil.
Elaeagnus plots at one location yielded 236 kg of mineral N/ha/yr in the upper 20 cm of soil, a value higher than previously reported for temperate deciduous forest soils in North America.

Elaeagnus conferta roxb is a kind of vivacious evergreen shrub.
The florescence of elaeagnus conferta roxb is from October to November, and its fructifying period is from March to April; the fruit is rich in nutrition and the edible rate of the fruits can be as high as 73.3 -91%.
Elaeagnus conferta roxb usually grow in mountain areas or in sunny valleys; sometimes, they even grow on Malachi trees and thus forms the miraculous scenes of "one tree growing on the other".

 A Great Seeder, Elaeagnus umbellata – Autumn Olive
Elaeagnus umbellata or autumn olive has become an invasive species in the eastern U.S. In contrast, this olive’s relative, Elaeagnus angustifolia, Russian olive is a problem in semi-arid western regions of the US, and is considered a small tree.
Elaeagnus umbellata is a large spreading, spiny-branched shrub often obtaining 3.5 to 5.5 m in height and 3.5 to 5.5 m in width.
Elaeagnus umbellata is native to China, Japan, and Korea and was introduced to North America in 1830 by Lake County Nursery (Dirr 1998).
