It is a perennial herb native[3] to North America, where it is found primarily in the southeastern United States. Its typical natural habitat is in dry woodlands and forests, although it can also be found in disturbed areas.
Mimosa microphylla is a sprawling vine with a prickly stem. It has compound leaves, with 4-8 pairs of small leaflets per leaf. Its leaves are sensitive to touch, and fold together immediately after being disturbed. It produces round heads of purple flowers from June to September.
