The genus Sambucus contains roughly 22 hardy, herbaceous perennials and deciduous shrubs and trees typically grown for their fruits, flowers and foliage. These are also known by the name elder or elderberry. Leaves are divided pinnately and arranged oppositely on stems. Flowers are produced in dense clustered arrangements which are either on equal length stems, forming a flat-topped structure called an umbel or on individual stalks on a branched stems known collectively as a panicle. These flowers are white or pink, with 5 petals and 5 white protruding stamens with yellow anthers. Flowers develop into clusters of black, white or red fruits.
