Mimosa Trees

Commonly known as the mimosa tree or silk tree, Albizia julibrissin is an attractive yet invasive tree that is threatening Florida's landscape.

Originally from China, the mimosa tree has been a popular landscape tree in Florida for many years because of its fragrant, showy pink flowers and feathery, fern-like foliage.

But this tree has a bad habit of taking over native Florida landscapes. Mimosa trees take advantage of sunny areas, growing up to forty feet tall. They can become a serious problem along rivers, where their seeds can be easily transported by water.

Due to its ability to grow and reproduce along roadways and disturbed areas, and its tendency to readily establish after escaping from cultivation, mimosa is considered a Category II invasive by Florida’s Exotic Pest Plant Council.

The best way to get rid of a mimosa tree is to cut it down at ground level when it begins to flower. To control resprouting, you’ll either have to cut off new growth or use a herbicide on the stump.

Seedlings can be pulled by hand, but make sure you get all the roots. Learn how to recognize this tree and take action to prevent its spread.
