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.
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.
