PlantFiles: Yakon, Yacon
Polymnia sonchifolia

Reply to Michael (ClimbTheMtns): The 2006 Seeds of Change catalog lists Yacon as a new offering this year. Their "eNewsletter #40" at seedsofchange.com has quite a detailed and enthusiastice writeup. What they have to say is based on their experience growing it " for the last few years from Maine to New Mexico and Oregon", which says something about where it can be grown. I, for one, will be trying to grow a couple of plants here in Chicago this Spring.

I'm trying to find a source to buy Yacon.
If anyone has a link please let us know here.

thanks,
Michael

Out of curiosity I grew this crop from a bought plant in partial sunshine. I t did not bloom. I t produced ca. 4lb of dahlia-like, elongated tubers from 1 plant. I harvested them a little late after a hard frost and some cracked and turned black. We peeled and sliced them, fried them briefly with onions in butter and then cooked them in the pressure cooker like potatoes or Jerusalem artichokes. They were very tasty.

I am yacon lecturer in selling our cooperative's main products, this Doalnara Yacon Tuber.
By researching I know Yacon originated in Peru, in Ecuador, South America and it has a real volume of production in such place. However, in the Philippine Doalnara Yacon Plantation, I can say, the tuber seemed to find a real home. Due to the fact that the soil is 100% organic, and the people cultivating are also organic. Funny, but what I mean, Philippine Doalnara Yacon is a real gift fruit and it does naturally heals these diseases: diabetics, hypertension, kidney diseases, constipation, insomnia. Some testimonial highlights about yacon are: it can even heal mosquito bites, dog bites, open wound, inflammation, bee sting, etc.
The cooperative is on global campaign for global restoration, which includes the restoration of the mentality, body and the environment. Practicing raw diet, indeed all products are chemical-free and 100% for the consumption is direct from the garden. Doalnara Yacon grow bigger (some 2 kilos per tuber) than other countries' yacon, and far medicinal, I can say.
Currently, we are exporting yacon in Japan and found out that for all the 61 suppliers of yacon in Japan, the Philippine Doalnara Yacon Tuber is indeed 100% yacon. Why? Because the farmers are practicing raw diet and the direct consumer of this yacon tuber, sure enough, chemical-free and far medicinal tuber.

In many respects similar in habit to Jerusalem artichokes. Anything left in the ground with a shoot on it will likely grow a new plant, but not superinvasive. South American origin. Small orange daisy flower. Large untidy plant, dying off in late autumn. Harvest tubers mid-late winter as you need them. Sweetness increases if they are left in the sun for several days, though slugs and snails make a meal of them if you aren't watchful. The tubers are up to 200mm (8") long and up to 75mm (3") across. I peel them and slice them into a salad, where they are slightly sweet, and textured somewhere between a potato and a crisp apple. They will absorb flavours from any herbs in the salad, such as coriander, fennel, etc. My German neighbour slices them into his muesli in the morning for breakfast, and they pick up a litle of the ground ginger and cinnamon in his cereal. The sugar present, inulin, contributes no calories as we do not digest it. Grown commercially on small scale in Northern New Zealand. Sweetness can vary from one source to another, though fairly consistent from same rootstock.
