Could I suggest this site, Stanthorpe, Qld. https://blog.nutri-tech.com.au/the-yacon-opportunity-a-gut-boosting-superfood/ It's May now and I am waiting and hoping my plants will flower soon so I can harvest the three tubers I planted.

Yacon - try other seed selling companies on the internet or contact Boondie Seeds and ask when will she have them back in stock. On her website go to vegetables then other seeds and you will find Yacon.
