Use in landscaping projects
Common lilac (Syringa vulgaris) is the classic flowering shrub of Central and Eastern European gardens, with large, intensely fragrant flower clusters in April–May. It is used as a solitary shrub, in groups, as an informal flowering hedge and in parks, school yards and traditional gardens. It is extremely frost-hardy and long-lived.
Planting and spacing
As an informal hedge, plant one shrub every 1–1.5 m; as a solitary shrub leave 2–3 m of space. It prefers sunny sites – in shade it flowers poorly – and tolerates calcareous soils.
Care and maintenance
Pruning is done right after flowering, as next year's flower buds form in summer. Spent flower clusters are removed, and suckers from the base are cut periodically. Once established it needs very little care.
Frequently asked questions
When should lilac be pruned?
Right after flowering; pruning in autumn or winter removes the flower buds.
Why is my lilac not flowering?
The most common causes are deep shade and pruning at the wrong time.
