Lilac Tree (SYRINGA RETICULATA) - 'Ivory Silk'
‘Ivory Silk’ Lilac carries huge clusters of heavy, creamy white blossoms in early summer. Although a Lilac, this member of the species is quite different in appearance than those with which gardeners are more familiar. Its upright habit is more consistent and flowers more generously than other varieties in this species. It has an oval or pyramidal form when young but spreads to a rounded shape as it grows older. The fragrance from 'Ivory Silk' is more suggestive of a Privet than a traditional Lilac.
Reaching 25 feet tall and 15 feet wide at maturity, 'Ivory Silk' is faster growing than the parent Japanese Tree Lilac. Grows well in USDA Hardiness zones 3-6 and has an oval, compact dense form. When selecting a planting site, be sure to provide full sun and well-drained soil conditions. Tolerates clay, loam, sand, acidic, and slightly alkaline soil types. Maintain evenly moist soil conditions, but not standing water. Moderately drought tolerant and soil salt tolerant. Prune only after flowering is past.
