Elaeagnus
Elaeagnus species
shrubElaeagnus is a diverse genus of deciduous and evergreen shrubs and small trees known for their silvery, narrow leaves and fragrant small flowers followed by berry-like fruits. Many species are hardy, drought-tolerant, and nitrogen-fixing, making them valuable for ornamental landscaping, hedgerows, and wildlife habitat. The genus includes popular ornamental varieties and nutritious food-producing plants.

Establishment
4-12 monthsYoung shrub with silvery-gray foliage establishing root system; growth appears slow initially
Water regularly during first year; mulch to retain moisture and moderate soil temperature; avoid heavy fertilization which promotes weak growth
Vegetative Growth
1-2 yearsShrub develops branching structure and characteristic narrow, elongated leaves with distinctive silvery undersides
Prune to shape desired form in late winter or early spring; nitrogen-fixing root nodules establish, requiring no fertilizer; drought stress actually benefits hardiness
Flowering
2-4 weeks, often in spring or fall depending on speciesSmall, four-petaled flowers appear in clusters along branches, typically fragrant (scent varies by species, some highly perfumed)
Do not over-fertilize or flowering may be reduced; maintain good sun exposure; allow flowers to remain for pollination if fruit production desired
Fruiting
8-12 weeks from flowering to ripe fruitSilverberry or goumi fruits develop from flowers; small, oval berries with papery sepals on one end, initially red or orange ripening darker
Cross-pollination improves fruit set; fruits attract birds and wildlife; maintain consistent watering during fruiting season if desired for harvest
Dormancy
3-4 months in cold climates; minimal in mild zonesIn deciduous species, leaves yellow and drop in fall; evergreen types retain foliage; growth slows significantly in winter
No watering needed in winter unless region is unusually dry; prune dormant season if needed; minimal maintenance required

Common Pests
-
Hand-pick or prune affected branches; tolerates light defoliation; neem oil for heavy infestations; rarely requires treatment
-
Spray with water to dislodge; increase humidity; insecticidal soap if severe
-
Dormant oil spray in winter; prune heavily infested branches; horticultural oil during growing season
-
Yellow sticky traps; insecticidal soap; neem oil; usually minor pest on established plants
Uses
Edible berries
CulinaryGoumi (Elaeagnus multiflora) and Russian olive (E. angustifolia) produce tart, slightly sweet berries rich in vitamins and antioxidants. Fruits can be eaten fresh, made into jams, syrups, or dried. [source]
Silvery foliage accent
OrnamentalThe striking silvery-gray narrow leaves provide contrast in mixed borders, creating a luminous effect, especially in evening light. Cultivars like 'Quicksilver' are prized for this distinctive ornamental quality. [source]
Wildlife habitat and food
EcologicalFragrant flowers attract pollinators and beneficial insects; berries feed birds and small mammals; nitrogen-fixing ability enriches soil naturally. Excellent for hedgerows and wildlife-supporting landscapes. [source]
Windbreak and hedgerow
HouseholdDense, hardy growth habit makes Elaeagnus ideal for windbreaks, screens, and boundary hedges in challenging sites with poor soil, salt spray, or drought conditions. [source]
Traditional uses
MedicinalVarious Elaeagnus species have been used in traditional Asian and Middle Eastern medicine for anti-inflammatory and antioxidant properties. Research continues on bioactive compounds in the berries. [source]

Harvest Tips
For Elaeagnus angustifolia (Russian olive) and E. multiflora (goumi): Pick ripe berries in late summer to early fall when fully colored and slightly soft; fruits continue ripening on shrub; some species prefer harvest after a light frost which sweetens flavor. For ornamental-only species, allow birds to harvest naturally. Wear gloves as papery sepals may irritate skin.
Fun Facts
- 🌱 Elaeagnus species form symbiotic relationships with nitrogen-fixing bacteria in root nodules (actinomycetes), allowing them to thrive in poor soil without fertilizer—similar to legumes
- 🌱 The name 'Elaeagnus' comes from Greek words meaning 'oil' and 'chaste tree,' referring to the oily appearance of the fruit coating
- 🌱 Some Elaeagnus species, particularly E. angustifolia (Russian olive), have become invasive in parts of North America and Australia, outcompeting native vegetation despite their ornamental and ecological value
