Sweet Olive Tree:

The Sweet olive, (Osmanthus fragrans) also known as tea olive or fragrant olive, is in the same Family (Oleacea) as the olive oil olive. Other Genera in the family are: Ligustrum (Privet), Syringa (lilac), Fraxinus (ash)

Synonyms:Olea fragrans, Olea ovalis, Osmanthus longibracteatus, Osmanthus macrocarpus

The sweet olive does not make a seed with appreciable oil and is not used for making oil. Olive oil that is late harvest and has a sweeter, more ripe flavor is sometimes referred to as "sweet olive oil" on restaurant menus, as opposed to an astringent, bitter Tuscan style oil. Bland refined olive oil is also referred to as "sweet olive oil" when it is sold in drug stores for softening earwax, etc.
