I've killed several myself Sandi. Amazonica/Polly I put in the unheated entry too soon this Spring I think. Down to 60 at night. Stingray died because I brought in too late last fall (too cold at night). A. infernalis and cuprea(?) I did in as well. I think the potting soil was too soggy. My guess is out of the bag MG (without the moisture crystals) is too heavy or holds too much water. That Purple Cloak of yours looks sweet.

This looks like a Xanthosoma to me.
