Russian Olive-Elaegnus angustifolia

A tree that can often grow in the desert where no other tree can grow might seem good at first, but it's turned out to be quite a nuisance. This is Russian olive (Elaegnus angustifolia), in the Oleaster Family (Elaeagnaceae). It was brought to the U.S. as a windbreak and has gone on to break many people as they try to remove it. It is thorny, grows rapaciously in wet areas, and can quickly out compete native vegetation.
The flowers are yellow, and later in the summer it will have dark-colored fruit that can float down streams and propagate this invasive species in other locations. The flowers have a strong smell. For lots more about Russian olive, click here.
