In a Nutshell:
* The flowers are white or creamy-white, the corolla with a tubular base to 4–6 mm long and a four-lobed apex 3–6 mm across, and a strong fragrance; they are produced in broad panicles 5–30 cm long and 3–20 cm broad in early summer. The fruit is a dry, smooth brown capsule 15–25 mm long, splitting in two to release the two winged seeds.
* It is grown as an ornamental tree in Europe and North America.
* Syringa reticulata (Japanese tree lilac, Chinese: bao ma ding xiang, Japanese: hashidoi) is a species of Lilac, native to eastern Asia: in northern Japan (mainly Hokkaido), northern China (Gansu, Hebei, Heilongjiang, Henan, Jilin, Liaoning, Nei Mongol, Ningxia, Shaanxi, Shanxi, Sichuan), Korea, and far southeastern Russia (Primorye).

* Easily grown in average, medium moisture, well-drained soil in full sun. Tolerates light shade, but best bloom is in full sun. Prefers organically rich, moist, slightly acidic soils with good drainage. Needs good air circulation. Good tolerance for urban conditions. To the extent practicable, promptly remove faded flower panicles before seed set. Prune as needed immediately after flowering. Best grown in cool summer climates, and not recommended for planting in the deep South below USDA Zone 7.
* No serious insect or disease problems. This is one of the easiest of the lilacs to grow. It reportedly has good resistance to some of the major pests of lilacs, such as powdery mildew, scale and borers. It has some susceptibility to additional diseases including blights, leaf spots, wilt and ring spot virus.
* Effective as a specimen in the landscape. Tree forms are effective along streets, in lawns, near decks/patios or in foundations. Shrub forms are effective in borders or small groups. May be used as a screen along property lines.
* Syringa reticulata is a tree lilac that typically grows as a small tree or large shrub. In tree form, it typically grows to as much as 30’ tall and 20’ wide with an oval-rounded crown. Its best ornamental feature is its showy, fragrant, creamy white flowers that bloom in upright panicles to 12” long in late spring to early summer (later than most other lilac species). more...
