Lilac (Syringa)

Syringa is a genus of deciduous shrubs and small trees in the olive family, grown for spring flowers that are often fragrant. Species and cultivars vary widely in size, flowering time, and flower color, so care should be matched to the selected lilac.

Many common garden lilacs bloom in spring, while some species and selections flower later. Green leaves are generally shed in autumn. The genus includes 13 accepted species and extends across a wide range of temperate regions.

Large common lilacs can work as hedges or specimen shrubs, while dwarf cultivars fit tighter borders; match the available space to the named species or cultivar. ## Maintenance Water newly planted shrubs while they establish and during prolonged dry weather. Pruning needs depend on the species and cultivar; where flower display matters, prune after flowering rather than cutting off the next season’s buds.
