Yacon is perennial in sub-tropical/tropical areas. Save some root pieces and treat as an annual in other areas.

Grows into a large plant ( about 2m/6ft) with flowers similar to sunflowers and Jerusalem artichokes.

The plants die down after frost but the roots are sweeter. To store, dig and dry out for a couple of days in the sun if possible. Store in a dry, cool, not freezing and dark place.

Any roots left in the ground will grow the following year except where there are frosts.

Culinary hints - cooking and eating Yacon

The large roots can be used raw in salads peel and chop. Sprinkle with lemon juice to prevent browning.
'In the Andes, they are grated and squeezed through a cloth to yield a sweet refreshing drink. The juice can also be boiled down to produce a syrup. In South America the juice is concentrated to form dark brown blocks of sugar called chancaca.' (Green Harvest)

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 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.

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.

I have just harvested about 5 kgs of yacon tubers and I was wondering how long they will last before cooking/eating and should they be kept in the fridge?? I am just trying to work out whether it is best to give most away or whether they will last until we eat them....5kgs is rather a lot of yacon!!! Can you overdose on it???

They may keep for a few weeks in the fridge. There is a YouTube video
