Hello I'm on the Gold Coast and came across this in Colombia recently and would like to plant some in my garden. Anyone know where I can find it up this way?

I have some plants. If you email me I am happy to share some tubers. I am in Hobart but can probably get some to Launceston.

I live on the mid north coast of NSW, my sister gave me some yacon to try also one sprouting, unfortunately I think I might have killed it with kindness and am looking to get more tubers for growing and also is there anywhere in our area where I can purchase to use as have used in salads and in stir fries and thoroughly enjoy their freshness and texture.

You can often get small plants and the tubers for eating from Colin Amos at the Wauchope Farmers Market.

you can plant it now in July in the middle of winter frost, but it won't come up till it starts getting warm. Mine are in the ground at the moment, and we get frosts till early November. It will come up when it's ready.
