Elderberry, or American elder (Sambucus canadensis), is a small tree, rarely getting larger than 12 feet tall. It is native to North America. Its sibling, the European elderberry (Sambucus nigra) can grow up to 30 feet, and is found in Europe, Asia and North Africa.

The tree has been used in traditional folk medicine for centuries, and the fruits have been used to make wine and jams.

The berries are rich in vitamin C, and have been used, cooked or in wine form, as a remedy for sore throat, influenza and colds, and are also said to relieve asthma and bronchitis. The seeds, however, are toxic, and can induce vomiting and nausea if eaten.
