Olea europaea 'Sevillano' is a Mediterranean evergreen that transforms hot, dry climates into olive groves of silver-green foliage and gnarled character. This variety thrives in USDA zones 8-10, growing 15-30 feet tall with a rounded crown that becomes more architecturally dramatic with age. Fragrant white flowers bloom in early summer, followed by edible fruit on trees that become increasingly drought-tolerant once established. In colder regions, it grows beautifully in containers and conservatories, bringing the essence of Mediterranean gardening indoors.

Young olive trees arrive with smooth gray bark that develops a picturesque gnarl over decades, creating a living sculpture in the garden. The opposite, elliptic leaves are gray-green on top and shimmering silver-green beneath, giving the canopy constant movement and light play. Fragrant white flowers appear in early summer on panicles up to 2 inches long, followed by edible fruit that matures against this elegant foliage backdrop. Once established, this tree handles drought with remarkable resilience, thriving in the hot-dry summers and mild-wet winters of Mediterranean-type climates like California.
Olives are harvested at different stages for different purposes: green (unripe) for table olives that are cured and eaten whole, or fully mature black olives for pressing into oil or curing. The fruit from this variety can be cured through various traditional methods, fermented in brine, or pressed for extra virgin olive oil depending on harvest timing and processing preference.

Seeds require warm conditions to germinate, ideally between 60-70°F. Start seeds indoors in a seed-starting mix about 8-10 weeks before the last spring frost.
Transplant seedlings outdoors after all danger of frost has passed and the soil has warmed. Harden off gradually by exposing seedlings to outdoor conditions over 7-10 days before planting in their permanent location.
Harvest olives based on intended use: pick green (unripe) olives for table use, or allow them to fully mature to black for oil production. Mature fruit will detach from the branch with gentle pressure when ready. Harvest typically occurs in late fall through winter, depending on your climate zone.
Prune to shape the young tree and develop a strong framework as it grows. As the tree matures, light pruning maintains form and removes any crossing or damaged branches. Mature trees develop their characteristic gnarled appearance naturally and require minimal intervention beyond removing dead wood or shaping for desired form.
