Dioscorea bulbifera, commonly known as air potato or bitter yam, is a perennial vine that originates from tropical and subtropical regions of Africa, Asia, and northern Australia. It is characterized by its rapid growth, often exceeding 60 feet in length, and its ability to produce aerial bulbils, which are potato-like growths along the stem. These bulbils and the underground tubers are sometimes edible, although certain varieties can be toxic and should not be consumed without proper identification and preparation. The vine has heart-shaped leaves, and its flowers are inconspicuous, with male and female flowers on separate plants.

Air potato is valued in traditional medicine and holds cultural significance among the Tiwi people of Australia. In cultivation, it is often used for its vigorous growth to quickly cover trellises, arbors, and fences. However, it requires careful management due to its potential invasiveness, especially in warm climates like Florida, where it can outcompete native species and disrupt local ecosystems. It prefers well-drained soil, partial to full sun exposure, and regular watering. In regions where it is not invasive, it can be an attractive and fast-growing addition to the garden.CC BY-SA 4.0
