Award-winner Syringa reticulata 'Ivory Silk' (Japanese Tree Lilac) is a large shrub or small tree with an oval to rounded crown. In early summer, a profusion of huge clusters, 6-12 in. long (15-30 cm), packed with fragrant, tiny creamy-white flowers adorn the tree. Flowering begins at a young age on this sturdy, compact tree. The blossoms give way to loose clusters of tan capsules that persist well into the winter months. The erect branches are clothed in lanceolate to ovate, dark green leaves that remain attractive in summer. Equally handsome is the lustrous, reddish-brown exfoliating bark with horizontal lenticels, reminiscent of cherry bark. Drought resistant and free of pests and disease, this Japanese Tree Lilac is attractive as a small landscape tree or large shrub. Use as a specimen.
