It is interesting to hear that you purchased the plant from Bunnings. Which suburb is this store in? If they don't have them anymore I will have to source the plant from somewhere else.

I heard Waldecks sells them. Quiet pricey though!

If you have not already read the comments in this forum, you should be able to purchase the plant from Waldecks in Sterling, Perth. Failing this, you can check out Green Harvest in Maleny, Qld. Google greenharvest.com Good luck.

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.
