Also known ans English dogwood, this deciduous shrub is native to southern Europe and Asia Minor, and is a member of the hydrangea family, Hydrangeaceae, that also includes tree anemone, waxflower, and common whipplea. The plant grows 10-12′ tall and has a stiff, straight stem and oval, dark green leaves that are 1.5-4″ long and have toothed margins. From spring into summer, racemes of 5-7 white flowers appear. The flowers are 4-petaled and have a strong sweet-scented fragrance of orange blossoms. The single flower forms are more fragrant than those of the double hybrids. Several cultivars are available including a dwarf form and ones with yellow foliage and variegated foliage. Mock orange is valued for it floriferousness and pleasant fragrance so is a good choice for fragrance and moon gardens but once it has ceased flowering it needs attractive companions. It tends to colonize by suckers, so requires attention if a colony is not wanted. The genus name, Philadelphus, honors the Egyptian king, Ptolemy Philadelphus (285-246 B.C.), reputed to be a gardener. The specific epithet, coronarius, comes from the Latin word corona, meaning crown, and refers its use in making garlands.
