Overview
Common Lilac (Syringa vulgaris) is native to the Balkan Peninsula and has been widely cultivated for centuries. It produces large panicles of highly fragrant flowers and can live for many decades with proper care.
Care Guide
Light
Full sun is best for maximum flowering. At least 6 hours of direct sunlight daily.
Water
Water regularly during the first few years. Established plants are quite drought-tolerant.
Soil
Well-draining, slightly alkaline soil is preferred. Avoid heavy, waterlogged ground.
Climate
Needs a cold winter to bloom well. Performs best in cooler climates.
Pruning
Prune immediately after flowering. Remove spent flower clusters and thin older stems to encourage new growth.
Suckers
Many lilacs produce suckers. Remove them if you want to keep a single-trunk form.
Propagation
Can be propagated by softwood cuttings, layering, or by removing and transplanting suckers.
Common Problems
- Powdery mildew – Common in humid conditions; improve air circulation.
