Syringa villosa Vahl, commonly known as the Late Lilac or Villous Lilac, is a robust shrub belonging to the Oleaceae family. This species can reach heights of 2-4 meters, featuring sturdy, erect branches with a distinctive gray-brown bark.

The leaves of S. villosa are opposite, simple, and deciduous. They are ovate to elliptic in shape, measuring 5-12 cm long and 2.5-6 cm wide. The leaf surface is dark green and slightly glossy above, while the underside is paler with a fine pubescence, giving it a powdery appearance. This characteristic is reflected in the species name ‘villosa’, meaning ‘hairy’.

The inflorescence of S. villosa is a terminal panicle, typically 10-20 cm long, emerging from the terminal buds. These conical flower clusters are upright and emit a pleasant, though less intense fragrance compared to common lilac (S. vulgaris). The individual flowers are tubular with four spreading lobes.

The calyx is small with four acute or obtuse teeth. The corolla color varies from pale lilac or pinkish to almost white, lacking the deep purple hues found in some other lilac species. As the flowers mature, their lobes spread at right angles, forming a shape reminiscent of a cross when viewed from above.

Flowering occurs later than most lilac species, typically from mid-May to early June, depending on the climate. This late-blooming characteristic gives rise to its common name, ‘Late Lilac’. The fruit is a dry, oblong capsule, maturing in September and containing winged seeds.

Native to northern China, S. villosa naturally occurs in various habitats including hillsides, thickets, along watercourses, and in open woodlands at elevations between 1200 and 2200 meters. Its adaptability to different soil types and climatic conditions, coupled with its resistance to pests and diseases, makes it a valuable ornamental shrub in gardens and landscapes.

In cultivation, S. villosa is prized for its hardiness (USDA zones 3-7), tolerance to urban conditions, and its late-blooming period which extends the lilac season. It is often used in mixed shrub borders, as a specimen plant, or in naturalistic plantings. Regular pruning after flowering helps maintain its shape and encourage vigorous growth.

While not as widely cultivated as S. vulgaris, the Late Lilac has contributed to the development of several important hybrid groups, including the Preston lilacs (S. × prestoniae), which combine its hardiness and late-blooming traits with a wider range of flower colors.
