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)

Hi! I am Catharina and would like more information on this wonderful yacon plant which I would love to grow in my garden. I live in Putaruru in the South Waikato. We do get some frost but the general climate is mild. I am making an area with lots of organic siledge witch would keep the soil pretty warm and weed free.
