Russian Olive Elaeagnus angustifolia
ABOUT
Elaeagnus angustifolia, commonly known as the Russian olive, is a visually striking plant characterized by its narrow, willow-like leaves which have a silvery undersurface due to tiny scales. The upper surface of the leaves also has a dull green color that adds to the plant's unique color palette. During the blooming season, the Russian olive produces small, yet fragrant, yellowish flowers, giving off a pleasant aroma that adds to its appeal. The flowers are often hidden amidst the foliage but can be spotted by their strong scent. Following the flowering period, the plant bears olive-shaped fruits. These fruits begin with a silvery hue and gradually ripen to a reddish-brown color by autumn, providing a sharp contrast to the foliage. The bark of the Russian olive is also a notable feature. It has a distinctive dark brown coloring with deep fissures and a somewhat rough texture. As the plant matures, the branches may take on a twisted and contorted appearance that adds a rugged beauty to the overall aesthetic. Altogether, the Russian olive has a graceful, yet hardy appearance that makes it a popular choice for ornamental use in landscapes where its tolerance to various conditions is valued. Given its aesthetic qualities, the Russian olive provides a silvery-green hue to gardens, often accompanied by other plants which complement its unique appearance.

- Water
For Russian olive, establish a deep watering schedule during the first growing season to create a strong root system; water deeply every week with several gallons of water. Once established, the Russian Olive is drought-tolerant and may only need supplemental watering during prolonged dry spells. During these dry periods, provide a deep watering every two to three weeks, ensuring the water penetrates deep into the soil. Adjust watering in response to rainfall, lessening the amount when precipitation provides sufficient moisture. Water sparingly in winter when the plant is dormant.
- Light
The Russian olive thrives in full sun but can also tolerate partial shade. The ideal spot for this plant would be an area where it receives at least six hours of direct sunlight daily. While the Russian olive is adaptable, it performs best in locations that provide ample sunlight to encourage healthy growth and fruiting.
- Temperature
Russian olive is quite hardy and can tolerate a wide range of temperatures; it can survive in temperatures as low as -30 degrees Fahrenheit and as high as 100 degrees Fahrenheit. However, the ideal temperature conditions for the Russian olive are between 60 and 80 degrees Fahrenheit. Excessive heat or cold may stress the plant, so sites with moderate temperatures are preferred.
- Pruning
Pruning Russian olive is important to maintain its shape and to remove any damaged or diseased branches. The best time for pruning is during the dormant season, late winter or early spring before new growth begins. Prune the plant every two to three years, thinning out old branches to allow light and air to reach the center of the canopy.
- Cleaning
As needed
- Soil
Russian Olive prefers well-drained soil with a pH range between 6.0 and 7.5. A mix of loam, compost, and sand is ideal to ensure adequate drainage and fertility. It is tolerant of poor soils, including saline ones.
- Repotting
Russian Olive typically does not require frequent repotting as it is often grown as an outdoor tree. When grown in containers, it may need repotting every 2 to 3 years to prevent root-bound conditions.
- Humidity & Misting
Russian Olive is highly adaptable and does not require specific humidity conditions. It thrives in average outdoor humidity levels, making it versatile for different climates without special requirements.
- Suitable locations
Indoor
Place in bright light, minimize watering, allow soil to dry.
Outdoor
Full sun, well-drained soil, drought-tolerant once established.
Hardiness zone
2-8 USDA.
- Life cycle
Commonly known as Russian olive, Elaeagnus angustifolia begins its life cycle from seed, with germination typically occurring in spring after stratification breaks dormancy. Seedlings emerge and establish a root system, entering a phase of vegetative growth and developing leaves and stems. As the plant matures, it transitions to a reproductive stage, often after a few years, producing small, fragrant, yellowish flowers that rely on wind and insects for pollination. Following successful pollination, the flowers develop into silver-colored, olive-like fruits, which mature and are eventually dispersed by birds and other animals, aiding in the spread of the species. The Russian olive is deciduous, shedding its leaves in autumn and entering winter dormancy, during which it conserves energy and resources until favorable conditions return in spring, thus restarting the annual growth cycle. Russian olive can live for several decades, and over time, the plant may form dense thickets via root suckers, ensuring its persistence within an ecosystem and potentially reaching the climax stage of its life with mature, fully developed stands.
- Propogation
Propogation time
Late Winter – Early Spring
The Russian olive (Elaeagnus angustifolia) is most commonly propagated using seeds. The best time to propagate by seed is in the fall after the seeds have matured. To ensure good germination, the seeds often require a period of cold stratification, which involves mixing the seeds with moist sand and storing them in a refrigerator at 40 degrees Fahrenheit (4.4°C) for about 60 days. After stratification, the seeds can be sown about a quarter-inch deep in well-draining soil and kept at a constant temperature of around 70 degrees Fahrenheit (21°C) to promote germination. Once sprouted, the seedlings can be grown on in individual pots before being transplanted outdoors after the risk of frost has passed.
