Safety Overview
1.Black Elderberry — Essential Profile
Black Elderberry, known scientifically as Sambucus nigra subsp., is a widely recognized deciduous shrub or small tree belonging to the Adoxaceae family. Native to most of Europe, parts of North Africa, and extending into Western Asia, it has been naturalized and cultivated in various other regions globally, including parts of North America and Australia.
The plant typically grows to 6 meters (20 feet) tall, occasionally reaching 10 meters (33 feet), featuring a relatively shallow, spreading root system. Its bark is light grey, corky, and furrowed with age.
The genus Sambucus includes several subspecies, with Sambucus nigra L. ssp. nigra being the European black elderberry, while ssp. canadensis and ssp.
cerulea are native to North America. Its distribution extends across Europe (with exceptions in parts of Scandinavia and Russia), reaching altitudes of 900 m in the Tatra Mountains and up to 2200 m in the Atlas Mountains. The leaves are opposite, pinnately compound, usually with 5-7 (sometimes 3 or 9) ovate to elliptical leaflets, each 5-12 cm long, with serrated margins and a pointed apex. When crushed, the leaves emit a distinct, somewhat unpleasant odor.
In late spring to early summer, Black Elderberry produces abundant creamy-white flowers, arranged in large, flat-topped cymes (umbel-like clusters) up to 20 cm in diameter. These fragrant flowers are hermaphroditic and attract numerous pollinators.
Following successful pollination, the flowers develop into small, glossy, dark purple to black drupes (berries), typically 3-5 mm in diameter, which ripen in late summer to early autumn. Each berry contains several small seeds. The fruit hangs in drooping clusters, providing a striking contrast against the foliage.
Ecologically, Sambucus nigra subsp. thrives in a variety of habitats, commonly found in woodlands, hedgerows, forest edges, and disturbed areas such as roadsides and abandoned fields. It prefers moist, nitrogen-rich, base-rich, and phosphate-rich soils but is remarkably adaptable to a wide range of soil types, provided there is adequate drainage.
Its hardiness and adaptability have contributed to its broad distribution, with seed maturation requiring specific mean temperatures.
