Albizia julibrissin leaves and flowers

The fresh green to yellow green, Acacia-type leaves of Albizia julibrissin are bipinnate. A leaf comprises six to twelve pairs of opposite pinnae that bear from 20 to 30 pairs of oblong to elliptic, overlapping leaflets. The feathery leaves are delicately textured. Leaf dimensions are from 20 cm to 45 cm long and from 12 cm to 25 cm wide.

The nearly spherical and fluffy inflorescences are dense, dominated by massed, brush-like, white and pink, long-filamented stamens. The straight (when fully developed) filaments have white bases and are from 2 cm to 3 cm long. Calyces and corollas are small and insignificant.

The clusters of ovoid buds are pale green, resembling bunched grapes. The stamens are darker, deeper pink coloured when the calyces are freshly burst open and the stamens not yet straightened. 

Flowering happens mostly in summer.

Butterflies, bees and birds act as pollinators (iNaturalist; Wikipedia; https://www.gardenia.net).
