Care Guide

Ornamental & Landscape Value

Seasonal Interest:

  • Bloom Information: Blooms in mid-to-late spring. Features dense clusters of double magenta-purple flowers.
  • Fall Colour: Foliage remains green or turns a faint yellow-green before dropping.
  • Bark: Smooth and gray when young, becoming more textured and furrowed with age.
  • Winter Interest: Sturdy, upright branch structure provides a classic winter silhouette. 

Garden Value:

A spectacular choice for a fragrant focal point, flowering privacy screen, or mixed shrub border. Its upright habit and dense growth make it an excellent backdrop for smaller perennials.

Wildlife & Human Value:

  • Wildlife Value: Attracts butterflies, hummingbirds, and bees looking for early-season nectar.
  • Human Value: Provides a legendary fragrance for the garden and home; adds significant vertical interest and privacy to the landscape; stems are highly sought after for spring bouquets. 

Planting & Care Guide

Planting Considerations:

  • Best Time To Plant: Spring or fall.
  • Spacing: 8–10 feet apart for individual plants; 6 feet apart for a dense, flowering hedge.
  • Location Tips: Choose a spot with excellent air circulation to keep the foliage healthy. Avoid planting in low-lying "frost pockets" that can damage early buds.

Care:

  • Light Requirements: Full sun (at least 6–8 hours daily).
  • Moisture Requirements: Consistent moisture is best; do not allow the soil to become bone-dry.
  • Maintenance: Low to moderate. Prune immediately after flowering to shape the plant and remove spent blooms.
  • Fertilization: Apply a balanced, slow-release fertilizer in early spring. Avoid excessive nitrogen, which can lead to more leaves but fewer flowers. 

Tolerances:

Cold hardy; urban pollution; deer and rabbit resistant.

Tips For Success:

If your soil is naturally acidic, add a small amount of garden lime annually to maintain the alkaline pH lilacs love. To keep the plant youthful, prune out the oldest one-third of the stems every 3 years.
