The Osmanthus aquifolium has leathery, deep green, glossy leaves with sharply serrated margins which is why non-professionals often think they are looking at a holly. The main differences are sweet olive has opposite leaves (hollies have alternate leaves), and sweet olive shrubs. At the end of autumn sweet olives bear tiny white flowers with pleasantly sweet fragrance. These fantastic mature specimens are supplied in 450L sized pot, and measure 300cm+ in height.
