Hi John in Tasi I have longed for a feed of fresh yams for 32 yrs and only ever have them when I go home and thats rare, sometimes they are not in season when I am there. I have just begun a nice garden and would love to grow them I am willing to pay for them. Cathy Peck

I came across this site/discussion while looking for references to the purple skinned-yellow (not white) fleshed Kumara in Australia. My mission is to get some to grow for my Kiwi wife who misses them. Can anyone help me?

I planted a few NZ yams (shop bought for consumption) at the beginning of spring. Did all the things recommended and waited for the tops to dieback before digging. So disappointed. Not one yam!!! Could they have been yams grown deliberately not to reproduce? Jan

Hello can you grow Oca in the tropics maybe during the cooler drieronths? No frost up here, just concerned about planting in the wet season as its ver hot 35 degrees plus most days.
