Sambucus canadensis, the American black elderberry, Canada elderberry, or common elderberry, is a species of elderberry native to a large area of North America east of the Rocky Mountains, south to Bolivia. It grows in a variety of conditions including both wet and dry soils, primarily in sunny locations. Each spring the plant is covered with clusters of tiny white flowers that are followed by purplish-black fruit. The flowers and fruit have applications in alternative medicine, though its sibling (common elderberry, or Sambucus nigra) is the species that is usually used for healing. 10-12' x 4-5' mature size, zones 3-10. Wants rich, acidic soil.
