This is a perennial herbaceous vine that has a taproot and usually has 3 to 6 foot stems. Sometimes it grows along the ground and over other plants. Other times, it finds vertical support such as a fence. The leaves are are doubly compound; that is, the petioles come off the stems and are divided into leaflets that, in turn, are divided into subleaflets. These subleaflets are less than 1/4 of an inch long and are prominently veined on the lower surface. The blooms are similar to the powder puff mimosa, but the plant is a scrambling vine and has thorns.

The blooms ... note that the leaves have folded because I had touched them.
