Try an internet seed selling website or nursery or Bunnings.

This is my first time growing also. I was wondering this also but yesterday notice a flower just starting. I would say just give them time.

Can yacon be grown as a container plant indoors in colder climates? How big of a container?

I would grow it in a "wicking barrel". Use a plastic 55 gallon drum and cut it in half, now you've got two. See how to make one on YouTube. Yacon needs pretty good light so put the barrel close to a large window or enclosed porch.

I wish I could find some yacon to grow! Would you tell me where you found yours. I've been wanting to grow ya on for years out here on the farm but haven't found the tubers.
