Olea europaea ‘Koronieiki’ is a Mediterranean olive variety valued for its silvery-green foliage, attractive evergreen form and excellent olive oil production. Originating from Greece, this variety is known for producing small, oval fruits with a high oil content, making it a popular choice for olive oil cultivation. Its narrow leaves and naturally graceful branching also give it ornamental appeal, bringing a classic Mediterranean look to gardens and landscapes.
Ideal for Mediterranean-style gardens, courtyards, feature planting and orchards, Olea europaea ‘Koronieiki’ thrives in a sunny, open position with well-drained soil. Once established, it is drought tolerant and generally low maintenance, making it suitable for water-wise gardens. Water regularly while young, allow the soil to drain freely and prune as needed to maintain its shape and encourage productive growth. Fruit production is best in a suitable climate with adequate sunlight and growing conditions.
