Sambucus nigra L.

Sambucus nigra is a species complex of flowering plants in the family Adoxaceae native to most of Europe and North America. Common names include elder, elderberry, black elder, European elder, European elderberry and European black elderberry. It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations.

It is a deciduous shrub or small tree growing to 6 m (20 ft) tall and wide (rarely 10m tall). The bark, light grey when young, changes to a coarse grey outer bark with lengthwise furrowing. The leaves are arranged in opposite pairs, 10–30 cm long, pinnate with five to seven (rarely nine) leaflets, the leaflets 5–12 cm long and 3–5 cm broad, with a serrated margin.

The hermaphrodite flowers are borne in large, flat corymbs 10–25 cm diameter in late spring to mid summer, the individual flowers ivory white, 5–6 mm diameter, with five petals; they are pollinated by flies.

The fruit is a glossy dark purple to black berry 3–5 mm diameter, produced in drooping clusters in late autumn; they are an important food for many fruit-eating birds, notably blackcaps.

There are several other closely related species, native to Asia and North America, which are similar, and sometimes treated as subspecies of Sambucus nigra. The blue or Mexican elderberry, Sambucus mexicana, is now generally treated as one or two subspecies of Sambucus nigra subsp. canadensis and Sambucus nigra subsp. caerulea.
