Sambucus is a genus of between 5 and 30 species of elder or elderberry shrubs or small trees in the moschatel family, adoxaceae. This genus is native in temperate-to-subtropical regions of both the Northern Hemisphere and the Southern Hemisphere. It is more widespread in the Northern Hemisphere.
This deciduous shrub prefers a sunny location and grows to 10 feet (3 meters) or more in a variety of soils. The leaves are pinnate with 5–9 leaflets (rarely 3 or 11). Each leaf is 5–30 cm (2.0–12 in) long, and the leaflets have serrated margins.
They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white). All parts of the elderberry are poisonous except the berries which are used for jellies, in winemaking and medicinal products.
Sambucus canadensis is a species of elderberry native to a large area of North America. It grows in a variety of conditions including both wet and dry soils, primarily in sunny locations.
Its leaves are arranged in opposite pairs with leaflets around 10 cm long and 5 cm broad. In summer, it bears large (20-30 cm diameter) corymbs of white flowers above the foliage, the individual flowers 5-6 mm diameter, with five petals. The fruit is a dark purple to black berry 3-5 mm diameter, produced in drooping clusters in the fall.
