    Dioscorea bulbifera ("Air Potato") is a species of Yam with tubers beneath the soil that resemble oblong potatoes. It is a fast growing, broad leaved perennial vine that can attain heights to 150'. The vine forms bulbils in the leaf axils which then sprout, forming new vines that grow into a thick mass. This plant is an invasive here in Florida, taking over and displacing native plants. Although the foliage is rather attractive, the small white flowers are rarely seen. The uncultivated variety of this plant found in Florida is considered toxic, containing the steroid diosgenin.
