Easily grown in average, medium, well-drained soil in full sun. Tolerates light shade, but best bloom is in full sun. Prefers rich, moist, slightly acidic to slightly alkaline soils. Needs good air circulation. To the extent practicable for a small tree, prompt removal of faded flower panicles before seed set will increase bloom in the following year. Prune immediately after flowering.

Noteworthy Characteristics

This Japanese tree lilac cultivar is a small tree or large shrub which typically grows 20-25' tall with a rounded crown. Creamy white, fragrant, single flowers are arranged in dense, terminal clusters (panicles to 12" long). Blooms later than most other species of lilac (late May to early June in St. Louis). Elliptic to ovate, dark green leaves (to 5" long). Attractive reddish-brown bark.


No serious insect or disease problems. This lilac is considered to be a low maintenance plant with excellent resistance to powdery mildew and other common lilac diseases. Young leaves are susceptible to frost injury in spring.
