I received a small cutting/rhizome of this from a plant exchange. I tried everything to get it to grow. At was a few small stems and leaves and as more rhizomes would spring up the existing ones would die off. Finally, the other day... I completely lost it :(

I'm wondering if anyone has any advise/experience for growing these (in MI). I want to try these again from seeds next year. I haven't found any of these already growing in any nurseries around me.

Thanks!
