Additional Information

The Lilac genus, Syringa, is composed of over 20 species and numerous cultivars and variants of shrubs to small trees. The most well-known feature of lilacs is their showy, many times fragrant, flower panicles. Lilacs prefer cooler climates. Leggy plants can be rejuvenated by a hard pruning in the winter, with less intensive maintenance pruning after flowering. Can be affected by powdery mildew, leaf spot, borers, and blight.
