Albizia julibrissin (known as Persian silk tree or mimosa) is native to Asia but was introduced to the United States in the 18th Century, where it’s commonly grown. It has fragrant, bottlebrush pink-white flowers, and fern-like leaves. Hardy throughout the UK, it makes an excellent tree for a sheltered, sunny spot, although it does take a while to come into growth in spring. In cold winters some newer parts of the tree can be susceptible to frost damage, but these can be pruned out with little or no impact on the tree itself.


Grow Albizia julibrissin in well-drained soil in a sheltered spot in full sun. Prune out frost-damaged growth in spring.

Is Albizia the same as mimosa?

Several plants are known as mimosa. These include the sensitive plant, Mimosa pudica, as well as Acacia dealbata, which is most commonly called mimosa. Albizia julibrissin is often called mimosa, particularly in the United States. All three plants have similar leaves.
