Common Lilac

<em>Syringa vulgaris</em>, the common lilac, is a deciduous flowering shrub or small tree in the family Oleaceae, native to the Balkan Peninsula of southeastern Europe. It has been widely cultivated and naturalized across Africa, Asia, Europe, North America, and Oceania, making it one of the most globally distributed ornamental shrubs. The common lilac typically grows in temperate climates, preferring well-drained soils and full sun exposure. It is renowned for its dense, fragrant flower panicles, which range from pale lavender to deep purple and appear in spring. The species has not been evaluated for its conservation status by the IUCN, reflecting its widespread cultivation and lack of known population threats. Common lilac is extensively used in horticulture and perfumery, with hundreds of cultivated varieties developed over centuries. Its flowers are a valuable nectar source for pollinators including butterflies and bees. The species typically blooms in late spring and can live for many decades in suitable growing conditions.
