Plant of the Week: Ivory Silk Tree Lilac

Ivory Silk lilac tree is our Plant of the Week this week. Tree lilacs come to us from Japan. They are medium sized trees, growing 20 to 40 feet tall and wide. As ornamental trees, they are excellent in the landscape or garden.

We at Grimm’s Gardens love lilac trees for their flowers and shiny green leaves. The white flowers erupt in large panicles in June, filling the air with their sweet fragrance. They are immediately swarmed by pollinators, including bees, butterflies, and flies.

The leaves of the Ivory Silk lilac tree are shiny green and look similar to the leaves on old-fashioned lilacs. In autumn, they turn yellow in color before falling.

Lilac trees need hardly any pruning. Just site them in a full sun to part sun location, away from the house or power lines. They grow in a vase shape, with many upright limbs.

Just like other lilacs, they can have issues with lilac borers, wet feet, and powdery mildew. I have seen less of a problem with lilac borer on the tree lilacs versus the shrubs. Plant them in areas where the soil is well-drained or sloping to prevent root damage from standing water.

I love Ivory Silk lilac tree because it stands out with its early summer blooms. It shows off panicles of creamy-white, fragrant flowers among rich-green foliage – Paul Kiekhaefer, Landscape Designer at Grimm’s Gardens
