Syringa x hyacinthiflora ‘Scentara® Double Blue’: Cool-Toned Double Blooms, Early Spring Fragrance

A Proven Winners® lilac with a fresh, modern colour palette, ‘Scentara® Double Blue’ is a very heavy bloomer that fills spring air with classic lilac fragrance. Cool purple buds open to intricate double florets, and the blooms take on a soft blue tinge as they expand, creating a refined, almost icy look in full flower. The upright habit gives it a clean silhouette that reads beautifully as a specimen, or as a focal point in a sunny border. When it’s in bloom, it delivers that unmistakable lilac moment, generous, fragrant, and wonderfully inviting.

Uses and Benefits: Use ‘Scentara® Double Blue’ as a specimen shrub near patios, walkways, and entry gardens where the fragrance can be enjoyed up close. Its cool-toned bloom colour pairs beautifully with both soft pastels and crisp whites, and it brings early-season excitement to sunny shrub borders. The flower clusters are also excellent for cutting, letting you bring that spring scent indoors. A strong choice for pollinator-friendly landscapes, it offers an early floral supply when bees are actively foraging.

Care Instructions: Plant in full sun for the fullest bloom and best performance. Water regularly during the first growing season, then provide moisture during extended dry spells, especially in sandy soils. Lilacs prefer good drainage, so avoid sites that stay wet. Prune right after flowering by removing spent blooms and, if needed, thinning a few older stems at the base to keep the shrub vigorous. Avoid late-season pruning, since next year’s flower buds form on current growth.

History: ‘Scentara® Double Blue’ is part of the Scentara® series, selected for abundant flowering, strong fragrance, and a garden-friendly habit. As an early flowering hybrid lilac, it helps kick off lilac season with cool-toned colour and reliable spring performance, making it a standout choice for sunny Canadian landscapes.

Final Thoughts: If you love lilacs but want a cooler, more tailored look, ‘Scentara® Double Blue’ delivers with richly double blooms and classic fragrance, all on a clean, upright shrub that feels right at home in both traditional and modern gardens.
