Common lilac cultivars

The right plant, the right place

Make room for something good.

The fragrant spring flowers suit a large border, informal hedge, or screen, and stems can be cut for arrangements. Choose a cultivar whose mature size fits the space.

Where to plant

Plant in full sun with room around the mature shrub for air movement. Check the cultivar’s expected width before placing it near paths or other shrubs.

Through the seasons

Fragrant flower clusters appear in spring, in colors determined by the cultivar. Green foliage is deciduous, and pruning belongs just after bloom.

Southwest Washington gardens

Give it a good start.

Common lilac has regional growing guidance, but cultivar performance varies. In milder Southwest Washington sites, some selections may flower less reliably because lilacs need winter chill.

Soil, drainage & water

Provide well-drained, neutral to slightly alkaline soil and moderate moisture. Check acidic soil before amending it, avoid persistent wetness, and water deeply during summer heat when needed.

A little care goes a long way

Growing well, season after season.

Prune immediately after flowering if shaping is needed. Removing faded flowers is optional; thin older stems to renew a crowded or leggy shrub.
