Plant Profile: Sweet Olive (Osmanthus fragrans)

Sweet olive Osmanthus fagransFor fragrance, sweet olive ranks with jasmine, gardenias, and honeysuckle. A native of eastern Asia, it is a large evergreen shrub or small tree that grows up to twenty to thirty feet tall and fifteen to twenty feet wide but is usually six to twelve feet high. When young it is upright and columnar but becomes vase shaped as it matures. The shiny medium-green leaves are finely toothed and are held at the ends of the stems. From fall to spring and sporadically during the summer, white to yellow or orange flowers are produced in small clusters. Although usually not very showy, they produce an very strong fruity fragrance that is variously described as apricot, peach, or citrus. This is an excellent plant to place as a specimen near a patio, walkway, window or other place where its fragrance can be enjoyed. Its columnar habit when young makes it a good plant for use in a hedge or screen and it can also be grown in a container and brought indoors in cold climates.
