Syringa reticulata

Syringa reticulata, the Japanese tree lilac.[1] is a species of flowering plant in the family Oleaceae native to eastern Asia, which is grown as an ornamental in Europe and North America.


It is a deciduous small tree growing to a height of 12 m (39 ft), rarely to 15 m (49 ft), with a trunk up to 30 cm (12 in), rarely 40 cm (16 in) in 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 (0.98–5.91 in) long and 1–8 cm (0.39–3.15 in) 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 0.16–0.24" (4–6 mm) long and a four-lobed apex 0.12–0.24" (3–6 mm) across, and a strong fragrance; they are produced in broad panicles 5–30 cm (2.0–11.8 in) long and 3–20 cm (1.2–7.9 in) 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.[2][3][4][5]


Syringa reticulata is found 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).[2][3][6]

The Latin specific epithet reticulata means "netted".[7]

  • Syringa reticulata subsp. reticulata (syn. Syringa japonica (Maxim.), also syn. S. amurensis var japonica (Maxim.) Franch et Sav.- Ligustrina japonica (Maxim.) ) - 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 has very distinct reddish-brown peeling bark.
