Sambucus canadensis, the American black elderberry, Canada elderberry, or common elderberry, is a North American species of elderberry.
It is a deciduous suckering shrub growing to 6 metres (20 feet) tall.[4] The leaves are arranged in opposite pairs, pinnate with five to nine leaflets, the leaflets around 10 centimetres (4 inches) long and 5 cm broad. In summer, it bears large (20–30 cm or 8–12 in diameter) corymbs of white flowers above the foliage, the individual flowers 5–6 millimetres (3⁄16–1⁄4 in) diameter, with five petals.
The fruit (known as an elderberry) is a dark purple to black berry 3–5 mm diameter, produced in drooping clusters in the fall.
