The flowers are yellow, produced in capitate flowerheads which are 5 to 10 cm in diameter, with 10 to 20 ray florets. The tubers are elongated and uneven, typically 7.5 to 10 cm long and 3 to 5 cm thick, and vaguely resembling ginger root, with a crisp texture when raw. They vary in color from pale brown to white, red or purple.

They can be cooked like a potato or even eaten raw if sliced thin. They are fairly high in fiber (inulin) so they may cause gas and bloating. Commonly found in specialty and gourmet food stores including Whole Foods. They are becoming more common now.
