Syringa reticulata (Japanese Tree Lilac; Chinese: 暴马丁香 bao ma ding xiang; Japanese: ハシドイ hashidoi) is a species of Lilac, native to eastern Asia: in northern Japan (mainly Hokkaidō), northern China (Gansu, Hebei, Heilongjiang, Henan, Jilin, Liaoning, Nei Mongol, Ningxia, Shaanxi, Shanxi, Sichuan), Korea, and far southeastern Russia (Primorye).[1][2][3]

Syringa reticulata is a deciduous small tree growing to a height of 12 m, rarely to 15 m, with a trunk up to 30 cm (rarely 40 cm) diameter; it is the largest species of lilac, and the only one that regularly makes a small tree rather than a shrub. The leaves are elliptic-acute, 2.5–15 cm long and 1–8 cm broad, with an entire margin, and a roughish texture with slightly impressed veins. 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.[1][2][4][5]

There are three subspecies:[1]

  • Syringa reticulata subsp. reticulata - Japan.
  • Syringa reticulata subsp. amurensis (Rupr.) P.S.Green & M.C.Chang (syn. S. reticulata var. mandschurica (Maxim.) H.Hara) - Northeastern China, Korea, southeastern Russia.
  • Syringa reticulata subsp. pekinensis (Rupr.) P.S.Green & M.C.Chang - North-central China.

It is grown as an ornamental tree in Europe and North America.[5]
