The oleaster, scientifically known as Elaeagnus, is a genus of flowering plants in the family Elaeagnaceae. These shrubs and small trees are known for their silvery leaves and fragrant flowers. Oleasters are often found in temperate and subtropical regions, thriving in well-drained soils and full sunlight. They are valued for their ornamental qualities and ability to tolerate poor soil conditions. In addition to their aesthetic appeal, oleasters produce small, edible fruits that are rich in nutrients. These fruits can be consumed fresh or used in jams and jellies. Oleasters also play a role in soil stabilization and are sometimes used in reforestation projects due to their hardy nature.
