(Alternanthera philoxeroides)


Alligatorweed grows close to the ground with reddish stems and sword shaped green leaves.


Reddish brown stems can be simple or branching, one to three and a quarter inches long. The stems form thick mats as they lay along the ground and curve upward. Leaves are opposite each other and can be sword shaped or oval shaped; they are thinner and immobile at the base. Smooth, thick, fleshy leaves grow three quarters of an inch to four and a quarter inches long and two-tenths of an inch to three-fourths of an inch wide. Sweet scented flowers have many white or silvery petals that form a roundish shape. The petals are narrow and about two-tenths of an inch long.


Alligatorweed can be found in California, Illinois, and the southeastern United States from Texas to Virginia and Florida.
