Mimosa, also known as silk tree, is a small tree that is 10 to 50 feet in height, often having multiple trunks. It has delicate-looking, bipinnately compound leaves that resemble ferns. The bark is smooth and light tan to greenish in color. Mimosa has very showy, fragrant, pink flowers. The flowers give way to small, flat pod-like fruits.
Mimosa is native to Asia and was first introduced into the U.S. in 1745. It has been widely used as an ornamental. Mimosa currently is found throughout the eastern and southwestern United States. It is widespread and common throughout Georgia.
Mimosa invades any type of disturbed habitat. It is commonly found in old fields, stream banks, and roadsides. The seeds, which are produced in abundance, are dispersed by animals and water, allowing this plant to quickly spread and invade new areas. Once established, mimosa is difficult to remove due to the long-lived seeds and its ability to re-sprout vigorously.
Recommended herbicides for control:
Trees: injection and cut stump – Arsenal AC or Garlon 3A
Saplings: basal spray – Garlon 4
Resprouts and seedlings: foliar spray – Garlon 3A, Garlon 4, glyphosate, or Transline
