Classic, slow-growing Mediterranean evergreen tree with willow-like foliage that can be grown as a standard or multi-trunk. Trunks of younger trees are generally smooth and become more gnarled as they age. Pollen is highly allergenic to many people, and fruit and seeds can be messy and even invasive. Seeds can be spread by birds and mammals and have become invasive in parts of southern California and the Central Valley. Low-flowering and non-fruiting cultivars are available.

Examples: O. e. ‘Bonita’ (25-30’ x 25-30’) is nearly fruitless; O. e. ‘Franz Fruitless’ (25-30’ x 25-30’) produces no pollen and nearly no fruit; O. e. ‘Little Ollie’ (6-8’ x 6-8’) is a dwarf non-fruiting hybrid with dense foliage; O. e. ‘Majestic Beauty’ (25’ x 20’) only develops small amounts of fruit; O. e. ‘Swan Hill’ (25-30’ x 25-30’) is a non-fruiting olive free of airborne pollen.
