Syringa reticulata 'Ivory Silk'
Ivory Silk Japanese tree lilac

Creamy white flower plumes brighten the canopy in late spring, followed by dark green summer leaves. The upright crown becomes rounder with age, and golden autumn foliage exposes shiny brown bark as it falls. This is a true small tree, distinct from familiar shrubby lilacs.
