This is a Caudex forming plant with large “warty” tuber and a long climbing vine. Flowers Are small white to green and star shaped, pollinated by fruit flies. native to the Kalahari desert, this plant has been used by the tribes of Namibia and South Africa as a famine food and water source. The root is said to be similar to a sweet potato in texture and flavor, but requires a specific cooking process to rid it of toxic alkaloids. Semi deciduous, water root will go dormant in winter as you decrease watering. It will lose some of its leaves, but come spring, it will start growing again. In the wild, the plant grows with the caudex mostly underground. Growing it this way will make the caudex grow faster, but many collectors raise the caudex in the pot to showcase its unique appearance.
