Silverberry

elaeagnus commutata

The Silverberry, or Elaeagnus commutata, is a resilient deciduous shrub or small tree native to North America, prized for its distinctive silvery foliage and fragrant flowers. Often found in open, sunny locations, it plays a vital ecological role by enriching soil through nitrogen fixation. Its hardiness and ability to thrive in challenging conditions make it an important species in many ecosystems, providing food and shelter for various wildlife. Despite its somewhat humble appearance, the Silverberry is a fascinating plant with a quiet strength and significant environmental benefits.

Habitat: Found in dry to moist open woods, clearings, riverbanks, prairies, and disturbed areas across its range.

Appearance

Silverberry is characterized by its striking, silvery-grey foliage, which is covered in tiny, reflective scales giving it a metallic sheen. The leaves are oval to lance-shaped, typically 2-10 cm long, and alternately arranged. In late spring to early summer, it produces small, yellowish, bell-shaped flowers that are highly fragrant, often hidden among the leaves. These develop into small, round to oblong, silvery-red, berry-like fruits (drupes) that ripen in late summer or fall, also covered in silvery scales. The plant typically grows as a multi-stemmed shrub, reaching 1 to 4 meters in height, sometimes forming a small tree.

Interesting facts

Despite its common name, the 'berries' are technically drupes, a type of fleshy fruit with a hard pit, similar to a peach or cherry.

Indigenous peoples traditionally used the plant for various purposes, including eating the fruit, using the strong fibers for cordage, and medicinal applications.

Silverberry is often planted in land reclamation projects and for erosion control due to its ability to thrive in poor soils and fix nitrogen.

The distinctive silvery appearance of Silverberry leaves is due to a dense covering of tiny, star-shaped scales called lepidote scales, which reflect sunlight and help conserve water.

Special abilities

Silverberry forms a symbiotic relationship with nitrogen-fixing bacteria in its root nodules, allowing it to convert atmospheric nitrogen into a usable form. This enriches the soil, benefiting itself and surrounding plants.

Thanks to its silvery, scaly leaves which reduce water loss, and a robust root system, Silverberry is exceptionally tolerant of dry conditions and poor soils.

Its edible, if somewhat mealy, fruits provide a valuable food source for various birds and mammals, particularly in late summer and fall, aiding in seed dispersal.

Diet & Feeding

As a plant, Silverberry produces its own food through photosynthesis, converting sunlight, carbon dioxide, and water into sugars. It absorbs essential nutrients and water from the soil through its roots.
