Olea Europaea is a tender evergreen that thrives in warm subtropical areas, growing to 10metres in height. It has opposite leathery, shiny, narrow dark-green leaves up to 6cm long. Small white flowers in the summer are followed by green olives which given a long enough period of warmth ripen to black. O. Europaea has light-grey bark which becomes particularly gnarled with age. This is a broad-leaved species that lends itself well to areas of deadwood.
