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.

We grew them with great success in Melbourne, I would dig them up in June and put the shooting rhizome back in the ground straight away with no issues

In July I planted some tubers I got from my relative in the Blue Mountains ...cold up there. Came back to Brisbane and left them lying around for a few days before I got round to finding a big enough garden bag/soil to plant in. Put them NOT too deep in organic compacted soil and in a week or two they shot up. Now in September they are growing very quickly and looking great. The tubers had gone a bit 'soft' before I planted them but all seems to have gone fine...so far. Not sure when they may reach flower and die back. Excited to see what happens.
