How to Grow Bloomerang Lilac

Bloomerang Lilac

Syringa vulgaris 'Bloomerang'

shrub

Bloomerang Lilac is a compact, deciduous shrub that breaks the traditional lilac mold by blooming twice per season—in spring and again in summer or fall. It produces fragrant purple flowers on new growth, making it highly ornamental and long-flowering. This reblooming variety is perfect for gardeners seeking extended color and fragrance from a single plant.

Growth Stages

1

Establishment

First 6-12 months

Young shrub focuses on root development; minimal flowering in first year

Water regularly during first season. Mulch around base (2-3 inches, not touching stem). Prune lightly to shape.

2

Spring Bloom

3-4 weeks (April-May depending on zone)

Fragrant purple flowers cover branches; plant is in full bloom typically in mid-spring

Deadhead spent flowers after first bloom to encourage reblooming. Avoid heavy pruning during flowering.

3

Summer Growth

6-8 weeks (June-July)

Plant develops new shoots and foliage after deadheading; new buds form on fresh growth

Maintain consistent moisture. Fertilize lightly with balanced fertilizer if desired. Monitor for powdery mildew in humid conditions.

4

Reblooming

3-4 weeks (August-September)

Second flush of fragrant purple flowers appears on new growth; lighter than spring bloom but still showy

Deadhead again if desired to extend blooming. Reduce deadheading in late summer to allow seed formation (natural signal to plant to slow).

5

Dormancy

November-March

Leaves yellow and drop in fall; plant enters winter rest with visible buds for next spring

Minimal care needed. Prune only for shape or diseased wood in late winter. Avoid pruning in fall.

Common Pests

  • Improve air circulation; avoid overhead watering. Spray with sulfur or neem oil at first sign. Plant in full sun and well-draining location.

  • Keep tree healthy and stress-free. Remove dead/damaged wood. Wrap young trunks in early summer to prevent egg-laying. Prune out infested branches.

  • Minor damage; remove affected leaves. Maintain plant vigor. Rarely requires treatment on established plants.

  • Spray with strong water stream; insecticidal soap or neem oil for heavy infestations. Attract beneficial insects.

  • Remove affected leaves; improve air circulation. Avoid wetting foliage. Disinfect pruning tools between cuts.

Harvest Tips

Bloomerang Lilac is ornamental; flowers are cut for fresh arrangements in spring and summer blooms. Cut flowers in early morning when stems are turgid. Remove lower leaves and split woody stem ends. Display in cool location; change water every few days. Enjoy fragrance for 1-2 weeks in a vase.

Fun Facts

  • 🌱 Bloomerang Lilac is a breakthrough cultivar developed through selective breeding to overcome the traditional lilac's single-season bloom habit—it was formally introduced to the market in 2008.
  • 🌱 Unlike regular lilacs that flower only on old wood, Bloomerang flowers on new growth, making spring deadheading the key to triggering the summer rebloom; removing spent flowers signals the plant to regenerate and bloom again.
  • 🌱 A single Bloomerang shrub can produce hundreds of fragrant flower clusters over a season, providing more blooms and fragrance than three or four traditional lilac varieties combined.
