Scentara® Double Blue Lilac (Syringa x hyacinthiflora 'Smnshbbl') is a cold-hardy, high-fragrance lilac bred for superior garden performance and market appeal. It combines richly fragrant double blooms, strong powdery mildew resistance, and an upright, uniform habit. Maturing at 6–8 feet tall and wide, it serves as a reliable solution for hedging, screening, and mass plantings in zones 2–8, where few flowering shrubs offer comparable aroma and structure.¶The blooms are dense clusters of purple-blue double florets, delivering early spring impact and a fragrance that surpasses standard lilacs. Its strong landscape utility, ease of care, and season-long presence make it an ideal addition to garden center shrub programs and professional designs focused on color, scent, and durability.
