I am on the east coast of Tasmania and would like to get hold of some Yacon plants. Does anyone have any available? I can collect north or south of the state. Thanks, Tony.

Hi Tony, I am in Hobart and have recently harvested my Yacon and have several clumps of Rhizomes/tubers available if interested. Happy to give away. They grow well here and multiply ++ I acquired my first tuber from a friend in Burnie (they grow well there) ... founder of Food Plants International, which has produced the largest database (fee online) of edible food plants in the world.

Hi I live on Pirongia in the Waikato and am wanting to grow some yacon. Does anyone have any crowns to share or sell. Because we are on the side of a mountain we don't get frosts so hopefully it will grow well. Thanks.

Hi Heather, Did you get any yakon when you inquired? I live in the village and have just been given a plant, we could share.

I grew one Yacon last year a couple of small tubers (just a taste) I have broken up the roots and put them into 200mm pots can I plant these into the garden now or should I dig them up and plat later if so when should I plant?. I live just north of Mackay Qld.

I have grown yacon for many years and I usually just replant immediately if I'm somewhere the frosts aren't too harsh. I live in a colder zone now so I have dug them up and put them inside and will replant after last frost date this year. You only replant the rhizomes, not the tubers. So dig them up, eat the tubers and replant the rhizomes into individual spots.

Mary, Waldecks currently have Yacon for what appears to be much less than the private sellers & they are healthy plants.
