The black elder is a shrub or small tree that reaches a height of 2-6m. Young branches are green, then they become grayish-brown, with a large number of yellow pores. The leaves are oppositely arranged (20-30 cm long), composed of 3-7 leaflets on short stems, elongated ovate, pointed with a wide wedge-shaped base, the edge of the leaf unevenly toothed. The upper side of the leaf is dark green, the lower side is lighter. The flowers are small, yellow-white, sessile or on peduncles, arranged in large shield-shaped inflorescences.
The fruit is a juicy, berry-like drupe of black color. Blooms in May and June, fruits ripen in August-September. Black purple fruits ripen late, at the end of September, sometimes even until November, when the leaves have already turned yellow. Black elder is a shade-tolerant plant. Propagated vegetatively, by root shoots or seeds.
Important! Without flowers and berries in season, black elder is difficult to distinguish from red elder, which is poisonous!

The fruits are harvested when they are fully ripe, August-September. Cut into bunches, spread in a thin layer, wrap, then dry in dryers, ovens or ovens at a temperature not exceeding 65C.
