Soil: Prefers loose, well drained soils, somewhat pH adaptable and tolerates high pH.

Possibly the most trouble-free lilac available. Japanese tree lilacs make excellent specimen plants, street trees, works in groups and near buildings. Resistant to powdery mildew.

Several cultivars are available including:

‘Chantilly Lace’ - Variegated variety with cream leaf edges.

‘Ivory Silk’ - One of the older varieties, but still one of the best. A heavy bloomer at a young age.

Ivory Pillar™ - An upright form that has performed well in ND trials, even in the drier western North Dakota sites.
