Osmanthus fragrans

Tea olive (also sweet olive or fragrant Osmanthus) produces clusters of not particularly showy flowers that have an extremely powerful apricot/orange fragrance. It is a small, upright, evergreen tree or large shrub that will typically grow to 10-15′ tall in cultivation, but may reach 20-30′ tall in its native habitat in Asia (Himalayas, China and Japan).Features oval, leathery, glossy green leaves (to 4″ long). Leaf margins may be smooth or finely toothed. Tiny white flowers appear in axillary clusters in spring, with some sporadic bloom through the summer and heavy blooming again in the fall.  (Courtesy of Missouri Botanical Garden Plant Finder)
