- Description
-
Fortune’s osmanthus is an artificial hybrid that originated in Japan well before the middle of the 19th century. It is presumed to be a cross of the fragrant tea olive (Osmanthus fragrans) and false holly (O. heterophyllus). This hybrid was brought to Europe by German botanist and physician Philipp Franz von Siebold. The genus name comes from the Greek words for fragrant (osme) and flower (anthos). The species epithet honors famed 19th-century Scottish plant hunter Robert Fortune, who first introduced the palm to Europe.
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.
Fortune’s osmanthus is a large dense, oval-rounded broadleaf evergreen shrub or small tree. The leaves are shiny and dark green with a spine tip. 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 plant blooms in the late summer and fall and has inconspicuous flowers that have a pungently sweet aroma.
The cultivar 'San Jose' was developed in California in 1934 by W.B. Clarke Nursery in San Jose, California, and was introduced in 1941.
This plant is frequently utilized in hedges, foundations, screens, as a specimen plant, or pruned into a small tree. When pruning, keep in mind that next season's blossoms will appear on new growth.
Quick ID Hints:

Insects, Diseases, and Other Plant Problems: This plant has no serious pest or disease problems. Scales and nematodes may be seen, and mushroom root rot may occur if the soil is too wet.
