Here a detailed explanation of Albizia Julibrissin is mentioned. The Persian silk tree or pink silk tree is a species of tree in the family Fabaceae, native to southwestern and Eastern Asia.

Albizia julibrissin is a small deciduous tree with a broad crown of level or arching branches, growing to 5–16 m (16–52 ft) tall. Its bark is dark greenish grey, becoming vertically striped with age. Its leaves are large and frond-like: They are bipinnate, divided into 6–12 pairs of pinnae, each with 20–30 pairs of leaflets. Individual leaflets are oblong, 1–1.5 cm (0.4–0.6 in) long and 2–4 cm (0.8–1.6 in) broad. The true leaves are 20–45 cm (8–18 in) long and 12–25 cm (5–10 in) broad. The flowers bloom throughout the summer in dense inflorescences, which resemble starbursts of pink silky threads. The true flowers have small calyx and corolla (except the central ones), with a tight cluster of prominent stamens, 2–3 cm long and white or pink with a white base.

It is widely planted as an ornamental plant in parks and gardens, grown for its fine leaf texture, flowers and attractive horizontal canopy. Other positive attributes are a fast growth rate, low water requirements and the ability to thrive planted in full sun in hot summer climates. Silk tree wood may be used to make furniture. Pink silk tree can be used to treat the effects of stinging nettle (Urtica dioica) by rubbing the leaves in hand and then applying to the rash area. Relief is almost instantaneous.

The fruits first appear in June and typically mature from August to September. The seeds are easily dispersed by the wind, water, or by animals. The seeds contain a neurotoxin when ingested can be toxic to livestock and dogs. The tree can tolerate a variety of soils and moisture conditions because its roots have the ability to produce nitrogen.

Persian Silk trees generally live 10-20 years
