Physiology
Ludwigia helminthorrhiza grows from the water's edge into the water and along the stem and roots develops 1 - 1.2 cm long white rootlets which function as floating bodies to keep the main plant floating on the surface. At each nodus, the plant may develop roots, which may reach through the water to the bottom of the water. The flowers have white petals and oval to almost round shaped leaves.[1][4]
