Persian lilac is a deciduous, perennial shrub or small tree in the olive family (Oleaceae) native across a broad region from Afghanistan to northern China. Persian lilac was once thought to be a hybrid between S. afghanica and S. laciniata , but both of these species are now treated as synonyms of S. persica . The species epithet is Latin for Persia, the country now known as Iran. Ironically, the species does not naturally occur in Iran. It performs best in organically rich, moist, neutral to slightly alkaline soils with good drainage and good air circulation. It should be planted in full sun and well-drained soil as it cannot tolerate soggy, wet conditions. It can be propagated by softwood cuttings. Persian lilac has an upright or globose form with slightly arching branches. It is a low-maintenance shrub that is smaller and more heat tolerant than common lilac ( S. vulgaris ) . In the spring it has enchanting pale violet flowers with an intoxicating fragrance that attracts butterflies. Effective as a specimen plant or in a group, Persian lilac makes a great informal hedge or screen. Plant along property lines or in a cottage garden. Insects, Diseases, and Other Plant Problems: Insect pests include scales, borers, leaf miners, and caterpillars. Very susceptible to powdery mildew so prune to keep the center open and air flowing. Additional disease problems include blights, leaf spots, wilt, and ringspot virus.
