Sambucus nigra

Subspecies

There are several other closely related species, native to Asia and North America, which were formerly treated as subspecies of Sambucus nigra, including Sambucus canadensis and Sambucus cerulea.

Etymology

The Latin specific epithet nigra means "black", and refers to the deeply dark colour of the berries. The English term for the tree is not believed to come from the word "old", but from either the Anglo Saxon ellaern, meaning hollow, or Anglo Saxon æld, meaning fire, because the hollow stems of the branches were used as bellows to blow air into a fire.

Wildlife value

The soft, very juicy fruit are an important food for many birds, including several that are otherwise primarily insectivorous and rarely take other fruit. A total of 22 species were observed eating elderberries, with the most important for dispersing the seeds being blackbird, song thrush, European robin, blackcap, and common starling, while blue tit and common woodpigeon were significant as seed predators.

S. nigra is grown as an ornamental shrub or small tree, especially in informal hedges, wildlife gardens and mixed borders. The species is also cultivated commercially for flowers and fruit. It is vigorous and adaptable, growing in sun or partial shade although it performs poorly in deep shade or dry conditions. It tolerates both wet and dry soils from sand to clay, but grows best on well-drained, organic-rich, slightly acidic soils, about pH 6.0–6.5.^{[citation needed]} Plants for commercial plantations are usually propagated from own-rooted hardwood cuttings taken from one-year-old shoots. Propagation from seed is less common because seedlings are variable and the seeds have dormancy requirements. Weed control is important during establishment, as black elder competes poorly with other plants.

Some selections and cultivars have variegated or coloured leaves and other distinctive qualities, and are grown as ornamental plants. S. nigra f. porphyrophylla has dark maroon or black leaves, and pale pink flowers.^{[citation needed]} Leaf colour in purple- or golden-leaved cultivars is usually strongest in full sun. Garden plants need little pruning, but established plants can be hard pruned in late winter or early spring to restrict size or encourage fresh ornamental foliage. In commercial orchards, dormant pruning is usually begun from the second year, removing dead, damaged or diseased wood and stems older than three years, as productivity declines on four-year-old branches. Annual coppicing to ground level is generally not recommended, since most commercial cultivars do not fruit on first-year canes.^{[citation needed]}

The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:

• S. nigra f. laciniata (cut-leaved elder)
• S. nigra f. porphyrophylla 'Eva' ('Black Lace')
• S. nigra f. porphyrophylla 'Gerda'

Food and drink

The dark blue or purple berries are edible though with an insipid flavour when fully ripe, but are toxic when immature. They can also be used to make jam, jelly, and wine. In Scandinavia and Germany, soup made from the elderberry (e.g. the German Fliederbeersuppe) is a traditional meal.

Commonly, the flowerheads are used in infusions, giving a drink in Northern Europe and the Balkans. These drinks are sold commercially as elderflower cordial or elderflower pressé. In Europe, the flowers are made into a syrup or cordial (in Romanian: socată, in Swedish: fläder(blom)saft, in Danish: hyldeblomstsaft / hyldedrik), which is diluted with water before drinking. The popularity of this traditional drink recently has encouraged some commercial soft drink producers to introduce elderflower-flavoured drinks (Fanta Shokata, Freaky Fläder). The flowers also may be dipped into a light batter and then fried to make elderflower fritters.

The berries may be made into elderberry wine. In Hungary, an elderberry brandy is made that requires 50 kilograms of fruit to produce 1 litre of brandy. In southwestern Sweden, it is traditional to make a snaps liqueur flavoured with elderflower. Elderflowers are used in liqueurs such as St-Germain, and in a mildly alcoholic sparkling elderflower 'champagne', although a more alcoholic home-made version can be made.^{[citation needed]}

Folklore

In early Scandinavian and English folklore, the tree was linked to a Goddess called the Elder Mother. Later, a myth that Judas Iscariot hung himself from the tree led to the name 'Judas Tree'.^{[citation needed]} The fungus Auricularia auricula-judae, which commonly grows on the tree, is connected with the same myth, having the old common name 'Jew's ear'.

Traditional medicine

The European Union's Committee on Herbal Medicinal Products (HMPC) has established a monograph for Sambucus nigra flower. The current monograph recognises traditional use of Sambucus nigra for relief of early symptoms of the common cold. The HMPC states that "although there is insufficient evidence from clinical trials, the effectiveness of these herbal medicines is plausible and there is evidence that they have been used safely in this way for at least 30 years."
