Russian olive

Russian olive (Elaeagnus angustifolia) is a deciduous shrub or small tree native to regions including the Bismarck Archipelago, Borneo, Jawa, Lesser Sunda Islands, Malaya, Maluku, New Guinea, Philippines, and Taiwan. Thriving in various habitats across these areas, Russian olive can grow up to 7 meters tall and is well-suited for hardiness zones 2-7. This plant prefers light (sandy), medium, and heavy (clay) soils with a pH range of 6 to 9.5, making it adaptable to diverse soil conditions. The distinctive features of Russian olive include its silver-gray foliage and small, fragrant flowers that precede the production of edible fruit and seed. It is known for its ornamental value and can be used in gardens and landscapes as a companion plant, hedgerow, or nitrogen fixer. Additionally, the gum from this plant has been utilized for various practical purposes such as animal feed, fire starter, and fragrance. While Russian olive's adaptability makes it a versatile addition to gardens, its potential to become invasive should be considered in cultivation. The plant's fruit and seeds are edible but caution is advised when consuming any part of the plant due to possible allergens or other compounds.
