Anyone out there grown Yakon before.

A friend of mine has just given me 5 Yakon plants to grow this year. I was just thinking has anyone on here grown this before, and what do you think of the tubers it produces , and or what does it taste like.
I understand it is a very big plant.

never heard of it before.

very interesting read though. sounds like an excellent idea if you haven't got the time to wait or space for fruit grown on trees.

i'm interested in giving a few a go next year. more to add to the list.

Hi and thanks for the replies and interesting links that everyone posted. I just spoke to my friend and he grew his out in the open last year. he said he got about 4kg from each plant and they store very well just like potato's.
I am looking forward to growing these Yacon plants. I am planning on planting the Oca in between them this year, lets hope it all works out well this year, and I get lots of yummy South American Veg to eat over the Christmas period.

Please keep us up to speed as they sound very interesting 

I think that is a good idea. Hopefully Kate and myself will be able to post some pictures during the season and keep everyone informed on how they are doing .

and let us know what it tastes like
