An architectural evergreen olive with silvery grey-green foliage and classic Mediterranean character. Suited to feature pots, entry statements, soft screening and avenues in Brisbane’s warm climate. Spring blossoms attract pollinators; ornamental fruit follows in warm spots. In warm SEQ, treat primarily as an ornamental (fruiting can be variable); best performance in full sun and freely draining soils.
Origin: Mediterranean region
Attracts: Birds & pollinators
