As an ex Kiwi I too despaired of ever tasting NZ Yams again Last year I was able to source some seed from another exkiwi and have a few growing very wellwith very healthy topsbut didnt know one had to mound them up like spudsI may have enough of a crop to supply some seed but we`ll just have to wait and see
