Olea europaea 'Wilson'
Light: Full sun; at least 6–8 hours of direct sunlight daily.
Water: Low water once established. Water deeply across the root zone, allowing soil to dry between irrigations. In Phoenix, established trees generally benefit from deep watering every 2–4 weeks in summer, adjusted for soil and heat; water newly planted trees more frequently.
Soil: Well-drained sandy, loamy, or gravelly soil. Tolerates alkaline desert soils but struggles with persistent moisture and poor drainage.
Mature size: Typically 25–30 feet tall and equally wide; older trees may grow larger.
Bloom: Spring; flowering is sparse or absent, with little to no fruit production.
Evergreen / deciduous: Evergreen.
Growth rate: Slow to moderate; faster with appropriate irrigation during establishment.
