This shrub is widespread throughout most of Europe, extending farther north and growing higher up in the mountains than the common elder, sometimes as high as the tree line. On the other hand, it is rarely found at elevations below 300 m in central Europe and is not native to Britain, though it is sometimes naturalized. It grows in similar places to the common elder, i.e. mostly on soils rich in humus and nitrogen.
It is a native of the Balkan Peninsula, mainly Bulgaria and Yugoslavia, where it grows mostly on rocky, limestone slopes up to more than 1000 m. In central and western Europe it is very popular as an ornamental shrub and is widely cultivated in parks and gardens. Many cultivated varieties are grown with flowers ranging in colour from white to red and violet; these are often grafted onto privet. Lilac is frequently found more or less naturalized in hedges, on banks and the edges of woods especially near built-up areas.
Common elder is a large shrub or small tree up to 10 m high, developing a broad crown and stern up to 30 cm in diameter. The pale grey bark becomes deeply furrowed and corky with age. The shoots are stout, grey, slightly angular in cross section and covered with numerous white corky pores. The opposite, ovate and semi-naked buds are located above a large leaf scar shaped like a half-moon. The white flower clusters, 12 to 20 cm across, appear in June; the fruits ripen in September.
This shrub is a native of northern and central China, where it grows on mountain slopes, and was introduced into the parks and gardens of western and central Europe almost 150 years ago. It is very popular for the abundance and brightness of its blooms as well as for its early flowering season. It is planted either as a solitary specimen, in groups or as a border plant alongside paths. It requires full sun if it is to bear a rich profusion of flowers and is moderate in its demands on soil moisture.
It is slightly sensitive to frost and its shoots are damaged by frost in severe winters. Propagation is by means of seeds and summer cuttings. Also widely cultivated in European parks is F. viridissima, with simple leaves, likewise a native of China. Cross-breeding of the two above species produced the hybrid x F. intermedia with simple and occasionally trifoliate leaves. This hybrid and its named forms, notably 'Spectabilis' and 'Lynwood' are commonly met with in gardens.
