Elaeagnus umbellata, also known as autumn olive, is a deciduous shrub native to Asia. This fast-growing plant can reach heights of up to 20 feet and has an upright growth habit. The leaves are dark green with a silver underside, giving them a distinctive appearance. In the spring, the plant produces fragrant yellow flowers, which are followed by small red berries in the fall.
Autumn olive is renowned for its hardiness and ability to thrive in poor soil conditions. It is often used for erosion control and as a windbreak due to its dense growth. Additionally, it plays a role in wildlife habitat restoration by providing food and shelter for birds.
However, it's important to note that Elaeagnus umbellata can be invasive in parts of North America, where it was introduced either as an ornamental plant or for erosion control. Its rapid growth and prolific fruit production make it challenging to manage once established.
In the 19th century, autumn olive was introduced to the United States to serve as windbreak hedgerows and for erosion control. By the 20th century, it had become a highly invasive weed throughout most of the country. When autumn olive is planted in poor soils, it has the ability to enrich the soil by fixing atmospheric nitrogen through its roots. As a result, planting it near orchards can enhance their yield.

In summary, while Elaeagnus umbellata offers unique foliage and ecological benefits, it should be planted cautiously outside its native range due to its invasive potential.
Autumn Olive: As its name suggests, the autumn olive is a tree that produces fruit in the fall. The small red fruits are quite attractive and resemble miniature olives, which is why the tree has this name. However, it is also a highly invasive species and has posed significant threats to native plants.
