Fruits bright red or pink, ovoid, 6–8 mm, fleshy, lepidote.

Discussion

The flowers of Elaeagnus umbellata are more densely clustered and umbel-like than in other species of the genus in the flora area. Originally introduced for soil conservation and as food for wildlife, it is not considered a good plant for home landscapes because it has a tendency to become weedy (M. A. Dirr 2009). The species thrives in acidic or basic soils and birds spread the seeds.
