Syringa oblata
Early lilac is an arching shrub that flowers before common lilac. Dense, very fragrant panicles open from pinkish‑lilac buds in early spring. Leaves are rounded and can develop purple‑red fall color. Plants favor full sun with moving air. This species is best where early bloom and some fall color are valued.
