Albizia julibrissin (Persian silk tree, pink silk tree) is a species of tree in the family Fabaceae, native to southwestern and eastern Asia. A. julibrissin is a small deciduous tree growing to 5–12 m tall. The leaves are bipinnate, 20–45 cm long and 12–25 cm broad, divided into 6–12 pairs of pinnae. The flowers are produced throughout the summer in dense inflorescences, the individual flowers with no petals but a tight cluster of stamens 2–3 cm long, white or pink with a white base, looking like silky threads. They have been observed to be attractive to bees, butterflies and hummingbirds. The fruit is a flat brown pod 10–20 cm long and 2–2.5 cm broad, containing several seeds inside. A. julibrissin is widely planted as an ornamental plant in parks and gardens, grown for its leaf texture and flowers. The broad crown of a mature tree makes it useful for providing dappled shade.
Albizias dried flowers and used for tea, and leaves can be prepared like the salad.
