Elderberries

Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus Adoxa. The oppositely arranged leaves are pinnate with 5–9 leaflets (rarely 3 or 11). Each leaf is 5–30 cm (2.0–11.8 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). The taxonomy of the genus Sambucus L., originally described by Linnaeus and hence its botanical authority has been complicated by its wide geographical distribution and morphological diversity. This has led to overdescription of the species and infraspecific taxa (subspecies, varieties or forms). Species recognized in this genus are: The genus occurs in temperate to subtropical regions of the world. More widespread in the Northern Hemisphere, its Southern Hemisphere occurrence is restricted to parts of Australasia and South America. Many species are widely cultivated for their ornamental leaves, flowers and fruit. Elder commonly grows near farms and homesteads. It is a nitrogen-dependent plant and thus is generally found near places of organic waste disposal. Elders are often grown as a hedgerow plant in Britain since they take very fast, can be bent into shape easily and grow quite profusely, thus having gained the reputation of being 'an instant hedge'. It is not generally affected by soil type or pH level and will virtually grow anywhere sufficient sunlight is available. In Northern California, elderberries are a food for migrating band-tailed pigeons. Elders are used as food plants by the larvae of some Lepidoptera species including brown-tail, buff ermine, dot moth, emperor moth, engrailed moth, swallow-tailed moth and the V-pug. The crushed foliage and immature fruit have a strong fetid smell. Valley elderberry longhorn beetles in California are very often found around red or blue elderberry bushes. Females lay their eggs on the bark. The pith of elder has been used by watchmakers for cleaning tools before intricate work. Traditional uses of Sambucus was for their berries. Ornamental varieties of Sambucus are grown in gardens for their showy flowers, fruits and lacy foliage. Native species of elderberry are often planted by people wishing to support native butterfly and bird species. Of the many native species, three are used as ornamentals, S. nigra, S. canadensis and S. racemosa.
