I am seeking Yellow Yam in Australia. I live in Perth Western Australia. I want to grow the yam for personal use. I think Jamaican Yam is of the plant species in the genus Dioscorea. Are you able to assist please?

I'd love to grow yams . I never ever see them here in NSW or Qld. In nZ they have the red orange and yellow. I'd be happy for any!!

Look up some seed selling websites to find some to buy. The guide here says to plant by Nov so you need to hurry.
