Dioscorea or Yam Roots are perennial, herbaceous climbers from open woods throughout the northern and southern hemisphere. They make vigorous stems emerging from a large rhizomatous rootstock in early spring and very showy, dense foliage on long vines. Winter hardy species from USDA climate zone 6 to 8 are ideal for any well drained soil at the base of trees or tall shrubs, where some species will wind up their stems up to 8 m in a single year. South American, subtropical, non winter hardy species are usually smaller and make short stems winding on the ground. Cooked and starch rich tubers from several species are used as food in Asia and the Americas, however we do not recommend to use any for human consumption and strictly sell all Dioscorea species as ornamental plants only! Sow seeds flat at a minimum of some 5°C from early spring to early summer in any rich, well drained soil in a sunny spot. Transplant rhizomes in autumn after foliage has yellowed. All are USDA Climate Zone 6, unless not noted differently. 10 seeds per package, respectively 1 bulbil or 1 rhizome per package.
