Japanese Tree Lilac - Syringa reticulata, Seeds
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, Korea, and far southeastern Russia.
It 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.

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.
Scarification: Soak in water, let stand in water for 24 hours.
Stratification: warm stratify for 60 days, cold stratify for 60 days.
