Unique Features: This is an actual tree form, not a shrub that is pruned or grafted to resemble a tree. The Ivory Silk Lilac is a cultivar of the Japanese Tree lilac that was selected for its smaller size, straight trunk and heavier bloom. Ivory Silk is even more disease and pest resistant than the shrub forms of lilac. It also blooms later than the shrub forms, usually in June, so it avoids the late spring frosts that can damage the flowers. At this time the weather is warmer, making the pleasant aroma of the blossoms more intense. The large, up to 1’ long panicles, have lilac scented, cream colored flowers. The lilac trees are a ‘clean’ plant, dropping only flower petals and leaves. The Ivory Silk does produce persistent seed heads but the seeds are not viable so there is no sprouting. The bark resembles that of a cherry tree and provides some winter interest.
