Syringa reticulata 'Ivory Silk'

Ivory Silk Tree Lilac

Ivory Silk Japanese tree lilac produces large clusters of creamy white flowers in late spring. Its spreading crown gradually rounds with age, and shiny brown bark remains visible after the leaves fall.

The canopy loses its leaves for winter. Autumn color includes yellow. Allow the natural framework to develop without crowding neighboring plants or paths.

Choose a sunny position with well-drained soil. Water during establishment and allow enough room for the developing crown.
