Grow your own delicious and nutritious tubers. I harvest the big ones, nice roasted, then replant the small ones. Should have a never-ending supply. I use mine as a screen in summer for privacy. I dry the stalks and use them like bamboo for small plant supports. And when they're really happy, they send up 7ft flowers. Will be harvesting more for posting as they slowly stop flowering. Best to plant in fall or spring. You will receive a similar amount as in the picture, enough that you will have an endless supply. Bit bigger now, as that was first crop later crops are bigger.
