Description: Syringa vulgaris 'Olivier de Serres' is a majestic French lilac cultivar celebrated for its opulent, double white blooms flushed with soft mauve-pink highlights. Flowering in mid to late spring, this deciduous shrub produces large, upright panicles that are densely packed and highly fragrant, creating a beautiful display and drawing bees, butterflies, and lilac lovers alike. The flowers open from pale mauve buds into frilly, almost pearlescent white double florets, giving a luminous effect against the backdrop of rich green, heart-shaped foliage. This cultivar enjoys a sunny position with well-drained, neutral to alkaline soil and thrives in Melbourne’s climate, benefitting from cool winters that encourage abundant blooming. With its upright, elegant growth habit and outstanding perfume, 'Olivier de Serres' makes an excellent specimen shrub, flowering hedge, or part of a traditional cottage garden setting.
