Chupa King - Being that I'm also located in Puna, if you decide you'd sell a small rhizome of your plant(s) let me know. Could pick up locally. I, too, am very interested in these. It seems my love for (and reasons to love) the Zingiberales only grows as time passes, and this is another member whom I'd love to have a presence in my garden.
Do they go dormant in Winter like other deciduous members of their family?
