Syringa is a genus of deciduous and woody shrubs known for their beautiful fragrant flowers and ability to survive cold and temperate climates. Native to Asia, Europe and South Africa, many varieties and hybrids of Syringa are grown worldwide as ornamental plants in gardens and landscapes.
The most common of all species is Syringa vulgaris which grows as a woody shrub up to 5 meters and produces fragrant lilac flowers in spring or early summer. However, a number of other cultivars and hybrids are grown commercially and described generally as Lilac. Some popular hybrids are Charles Joy Lilac, Sensation Lilac, Miss Kim, and Angel White Lilac.
Most of these verities grow into large bushes reaching 5 meters or more and require regular pruning after every flowering season. These bushy plants can be propagated easily from cuttings. Though the genus is known for lilac flowers, however, new verities produce flowers in all shades of lavender, dark purple, blue, pink and white.
Lilacs can be grown under full or partial sun in a fertile, slightly alkaline, and well-drained soil. Avoid over watering and feed them with some lime and well-rotted manure when flowering ends. Start each flowering season with application of a fresh layer of compost (in early spring) under the plant to controls weeds and retain moisture.
