This species originated in tropical Central and South America. Mimosa pudica is naturalised throughout the tropics.
Mimosa pudica is invasive in Kenya A. Witt pers. A weed of wetter coastal areas. It is mostly found in plantation crops, disturbed sites, pastures, waste areas, parks, lawns, gardens and along roadsides. A prickly, long-lived perennial , herbaceous plant or small shrub with a creeping prostrate or decumbent or sprawling habit. It usually only grows cm tall, but can reach up to 1 m or more in height when supported by other vegetation. Mimosa pudica is not the only member of the legume plant family Leguminosae to move in response to stimuli.
More species of Mimosa show sensitivity to touch, known as seismonasty. Other legumes , for example some members of the genera Neptunia , Acacia , Albizia and Samanea , respond to a lesser degree by showing 'sleep movements' nyctinasty in their natural habitats Barneby This involves the closing up of the leaves a few hours before dusk, and the re-opening of the leaves a few hours before dawn. It is thought that these 'sleep movements' aid water conservation as well as defence against herbivory.
Native to the Middle East and Asia, mimosa was brought to this country in by the famous French botanist Andre Michaux , who planted it in his botanic garden in Charleston, South Carolina. It grew quickly into a vase-shaped, flat-topped tree, 30 to 40 feet tall, and it loved the Southern climate.
The flowers, attractive to butterflies, hummingbirds, and colonial gardeners, ranged in color from nearly red to deep pink to flesh-pink to white. On one road-side near my home, there is a row of them, each a different color.
Here's the usual pink. And here's a white one. I really like the white, but I've never seen it for sale. The various colors are due to genetic variation, with pink being dominant.

Plant one mimosa in the yard and soon every house in the neighborhood has two or three mimosas. Mimosa adapts to almost any well-drained soil, laughs at heat and drought, and does not mind if you spray-paint the trunk white, hang tires from the branches, or park your pickup on top of its roots. In hort class, we called it a "pioneer species," because if you disturb the land, remove native vegetation, and open the tree canopy to light, it's one of the first trees to appear. That's why you see it growing along just about every highway and country road in the South.
Northerners be glad it doesn't like your cold winters, but with global warming, who knows how much longer you'll be free?
