Albizia julibrissin Syn.: silk albizia, silk acacia, Lenkoran acacia, silk tree, silk bush, gul-ebrishim. Albizia lenkoran is a heat-loving deciduous honey plant of the genus Albizia, the Legume family. In folk medicine, it is used as an anti-inflammatory agent for external and internal use, and also has anthelmintic properties. The average height of the plant is 6-9 meters, but individual specimens can reach 12 and even 30 meters. The tree of Albizia Lenkoran has a spreading umbrella-shaped crown with a diameter of up to 7 meters. The unpaired double-pinnate leaves of Albizia lenkoran consist of 9-14 lobes, reach a length of up to 20 cm, and have from 15 to 60 leaflets on each lobe. The color of the leaves is light green above, glaucous below, except for some varieties that may have brown leaves (for example, the variety "Summer Chocolate"). In adverse weather conditions and at night, the leaves are folded along the middle vein, after which the entire leaf droops. The flowers of Albizia Lenkoran are collected in large fragrant paniculate inflorescences with five-ray symmetry. They have many long stamens of whitish-yellow or pink stamens, protruding from small white-yellow flower covers. Albizia blooms from mid-June (July-August, depending on the climate), sometimes flowering lasts until September-October. The leaves remain green for a long time and fall off only after the onset of cold weather. The albizia fruit is a flat, oblong, multi-seeded bean, up to 20 cm long. It has a powerful, superficial root system. A light-loving, fast-growing tree that can live 50-100 years. Usually does not tolerate frost, but there are cases when the tree withstood frosts up to-15-16°C. Propagated by cuttings, layering and seeds. Albizia lenkoran is widely distributed in tropical and subtropical latitudes, mainly in the Eastern Hemisphere: in southern Europe, China, Japan, Taiwan, India, Nepal, Iran, Afghanistan, Pakistan. Recently, more and more often albizia is bred for decorative purposes in the Western Hemisphere. On the territory of the former USSR, Albizia lenkoran grows in the south of Azerbaijan in the Talysh Mountains, in the Crimea, as well as in the countries of Central Asia. The flowers of Albizia Lenkoran are collected in late May or early June, at the beginning of the flowering period. The bark is also collected in summer and autumn in dry sunny weather, finely cut. Raw materials are dried in the open air in the shade or in well-ventilated dry rooms. It is necessary to dry the raw material immediately after assembly to preserve all the useful properties. The collected and dried flowers of albizia should be mixed from time to time, so that they do not lose their aroma and useful properties. In addition to the flowers, the buds of Albizia Lenkoran are also collected, plucking them in May (before they bloom) and drying them in the open air.
