I have nothing to add on the edibility question but will comment that Zingiber mioga is so far the only Zingiber (or Hedychium, or Curcuma, or Globba, or ....) that has survived outdoors for me in NW Arkansas (USA) for more than one winter. I think I've killed about every one of the hardier hedychiums outdoors, though several do well in the unheated part of the greenhouse. Z. mioga seems quite hardy, and flowers every year, though as the flowers are at ground level I often miss them. I planted it in moderate shade, and it promptly moved itself out into fairly high light, where it seems very happy. Is anyone aware of other gingers that might be candidates here?
