Syringa vulgaris four-lobed apex 5–8 mm across, usually lilac to mauve, occasionally white. They are arranged in dense, terminal panicles long. The fruit is a dry, smooth, brown capsule, 1–2 cm long, splitting in two to release the two-winged seeds. "Syringa vulgaris" was first formally described by Carl Linnaeus in 1753 and the description was published in "Species Plantarum". The specific epithet ("vulgaris") is a Latin word meaning "common" or "usual". Lilacs—both "S. vulgaris" and "S." × "persica" the finer, smaller "Persian lilac", now considered a natural hybrid—were introduced into northern European gardens at the end of the 16th century, from Ottoman
1104 Syringa Calvin–Rehoboth Observatory in New Mexico, United States. Lightcurve analysis gave a well-defined rotation period of 5.1547 hours with a brightness amplitude of 0.27 magnitude (). According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, "Syringa" measures between 19.711 and 24.30 kilometers in diameter and its surface has a low albedo between 0.031 and 0.045. The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0434 and a diameter of 22.13 kilometers based on an absolute magnitude of 12.3. This minor planet was named after the genus
