The Ivory Silk Lilac tree (Syringa reticulata 'Ivory Silk') is a stunning, fast-growing ornamental tree prized for its large, fragrant white flower clusters and smooth, exfoliating bark. Ideal for USDA Hardiness Zones 3–7, this lilac variety thrives in full sun and well-drained soil, with multi-season interest with beautiful spring blooms, attractive summer foliage, and striking winter bark texture. Known for their low-maintenance nature and resistance to common lilac diseases, they are a favorite among landscapers.
