The Ivory Silk Lilacs do not resemble any other lilacs you might have on your property! This tree is loved by many gardeners for its impressive size and glorious flower clusters. This tree loves full sun and can grow to 30feet with a spread of 15feet.  The cream colour blossoms arrive in the summer and last around two weeks on the tree. Though most lilac blossoms are fragrant, the ivory sills are not. This tree grows at a medium rate and prefers well drained soil!
