Fruitless Olive
Olea europaea
A classic Mediterranean shade tree with silvery foliage and a sculptural trunk, bred to produce no messy fruit.
Hardy to about 15°F in low and mid desert; evergreen, heat-loving, and mildly frost tolerant.
AMWUA Notes
Low water; fruitless cultivars avoid staining fruit and greatly reduce allergy pollen.
Care Guide
Deep-soak every 2-3 weeks in summer once established; deep infrequent watering, since overwatering forces weak growth.
Prune in late winter to reveal the sculptural trunk and thin the interior; can be a single- or multi-trunk form.
Minimal; a light spring feeding is optional.
Olive scale on occasion; ensure good drainage to avoid verticillium wilt.
Fruitless cultivars produce little pollen or fruit; silvery evergreen foliage year-round.
Soil, Feeding & Propagation
Well-draining loam, native, or decomposed-granite soil; tolerates caliche, rocky ground, and alkaline pH 7.5–8.5
Needs well-drained soil.
Low feeder.
Named fruitless cultivars (Wilsonii, Swan Hill) grown from cuttings to stay true to type

Placement Tips
- •Broad 25 ft spread as a Mediterranean shade or courtyard tree; give it 20 ft of room.
- •Choose a true fruitless cultivar such as Wilsonii or Swan Hill to avoid staining fruit near hardscape.
- •Low litter and thornless, safe near pools and patios.
- •Limb up the sculptural gnarled trunk to feature it; full sun.
