The genus Sambucus comprises mostly woody species, shrubs and small trees. Red-berried elder is not native in Finland, but a naturalized garden escape, common in many parts of South-Finland. It is a poisonous shrub with spreading branches, thriving best on nitrogen-rich sites. Red-berried elder flowers early in the spring. Birds eat the berries, and spread the seeds. Forms with variously lobed and toothed leaves are known.
Black elder (also known as Elderberry, European elder, European elderberry and European black elderberry) resembles red-berried elder. But its berries are black and very tasty (when raw, a bit poisonous). The green parts of both elders are always poisonous. Black elder has been used as a medicine against flu.
