- Description
-
Osmanthus x fortunei is a hybrid of Osmanthus fragrans and Osmanthus heterophyllus. It is a large dense, oval-rounded broadleaf evergreen shrub or small tree that grows up to 15 to 20 feet tall and 6 to 10 feet wide. This plant blooms in the late summer and fall and has inconspicuous flowers that have a pungently sweet aroma. The leaves are shiny, and dark green, and in the upper part of the plant (adult morphology) the margins are entire, while those in the lower part of the plant tend to be toothed (juvenile morphology).
This hybrid was first introduced in 1856 to Holland by a German botanist, Philipp Franz von Siebold. The cultivar, 'San Jose,' was later developed in California in 1934 by W.B. Clarke Nursery in San Jose, California, and was introduced in 1941.
The genus name, Osmanthus, comes from two Greek words, osme meaning fragrance, and anthos meaning flowers. The specific epithet, fortunei, is named for Robert Fortune who introduced the plant to England in 1862.
This plant prefers full sun and moist, well-drained, acidic soil. It is tolerant of alkaline soils, pollution, and part-shade. It has a slow growth rate and seldom produces fruits. The plant is deer and rabbit-resistant.
This plant is frequently utilized in hedges, foundations, screens, as a specimen plant, or pruned into a small tree.
