Albizia julibrissin, commonly known as the Persian silk tree or mimosa tree, is a captivating deciduous tree with striking beauty and delicate, fern-like foliage. Native to regions of Asia, including Iran, Korea, and China, this ornamental tree has been embraced in various parts of the world for its aesthetic charm.
Standing at a moderate height, the Albizia julibrissin features a graceful, umbrella-like canopy that provides dappled shade, making it a favoured choice for landscaping in gardens, parks, and streets. The leaves of the tree have a feathery and elegant appearance. The leaves close during the night, a phenomenon called nyctinasty, which adds a unique dynamic to the tree’s behaviour.
One of the tree’s most distinctive features is its vibrant and fragrant blossoms. In the summer months, Albizia julibrissin adorns itself with an abundance of puffball-like, pink to reddish-hued flowers that form in clusters at the branch tips. These blossoms not only attract bees and butterflies but also contribute to the tree’s picturesque allure.
As autumn approaches, the tree transitions to its next visual phase, producing flat, brown seed pods that hang in clusters. These pods twist open to reveal seeds covered with a silken, thread-like substance, reminiscent of silk, which gives rise to its common name “silk tree.” These pods persist on the tree even after the leaves drop, adding an interesting textural element to its winter silhouette.
