Autumn Olive Vs Russian Olive — What’s Common in These Two Invading Plants?

Autumn olive Vs Russian olive is going to be a comparison between two such species that are totally different from others.

What we commonly see are the fancy reviews on the most fire plants out there in the world. Here on this site, we try to keep you updated with the most exotic ornamental plants that can fluently put life into your landscape.

But there are other plants in the world too.

Quite a few of them are known for their harsh nature, killing the ecosystem, and for their use in making delicious dishes.

Autumn olive and Russian olive are different species of the same genus named Elaeagnus. Both are exceptionally competent because of their ability to thrive even in poor environmental conditions.

That’s why they stand out from other plants — primarily known for their exotic delicacy — and are popular because of their invasive property.

Today we’ll see what is common between these two aggressors. And how they are slightly distinct from one another.

So, before going into Autumn olive Vs Russian olive, I am first going to clarify some essential terms.

What are Invasive Plants?

Invasive plants are non-native species of plants. They usually get out of control in the areas where they multiply wildly.

They compete with the native species (defeating them most of the time) and torment the ecosystem.

Autumn olive and Russian olive originate from the family Elaeagnaceae, having 70-80 species worldwide.

They have the unique property of fixing nitrogen in the soil.

They do relatively well even in poor soil conditions. Thus, they can deprive other native species of nutrients leading to their extinction.

That ultimately affects human health as it directly depends upon the ecosystem.

On the one hand, there are the native plants that effortlessly thrive, dominating the land. These rapidly growing native species are called the “Aggressive Species.” While on the other hand, the invasive plants tend to attack the others’ men land and dominate them.

Well, how do these plants get to these areas? The answer is quite simple. Naturally, there are only ways like dispersal through birds, insects, or even humans.

But they can also be made to go rough intentionally. As these types of plants are skilled in vanishing the native plants and destroying the biodiversity, they eventually turn the ecosystem bane.

Autumn olive is scientifically known as Elaeagnus umbettata.

It is common in North Carolina as an Invasive species. It is a pretty tough and resilient shrub or a small tree.

Being at the top tier, the Autumn olive invades many zones of the US and Europe. It can swiftly take over the areas, terrorizing other species of plants by meddling into the natural resources.

Autumn olive is a deciduous plant that can rapidly outrun other greeneries. Therefore, you should not root your beautiful plants near these species.
