Mock Orange — Mock-orange (Philadelphus; also Mockorange, Mock Orange, Syringa) is a genus of about 60 species of shrubs from 1 to 6 m tall, native to North America, Central America, Asia and (locally) in southeast Europe. Most are deciduous but a few species from the south of the genus’ range are evergreen. The leaves are opposite, simple, with serrated margins, from 1 to 14 cm long.
The flowers are white, with four petals and sepals, 1-4 cm diameter, and commonly (but not in all species) sweetly scented. The fruit is a small capsule, containing numerous small seeds. The bark is thin and flaky, finely shredding in longitudinal strips.
Mock-oranges are used as food plants by the larvae of some Lepidoptera species including The Engrailed.
Mock-oranges are popular shrubs in parks and gardens, grown for their reliable display of late spring flowers; the scented species are particularly valued. In addition to the species, there are numerous garden origin hybrids and cultivars available.
