NOTE: this plant formerly known as Curcuma flaviflora, has now been described and named as Curcuma rubrobracteata. It grows to about 2 1/2 ft. tall and prefers shade. It is listed in one mail order catalog as being hardy to zone 8. One or my ginger growing friends from North Carolina offered the following explanation about the unusual shape of the rhizome and flowers. "With other curcumas a thin root is attached from the rhizome to the food storage tuber but with flaviflora the food storage tubers are attached directly to the rhizome. It is my experience that this is one of the most cold hardy of the curcumas. Curcuma flaviflora's bloom is central but splits out of the main stem just before emerging from the soil. This gives the impression that the bloom is on a separate stalk."
This is one ginger that is very hard to find and very expensive when you do find it. I don't have a whole lot of it but wanted to list it to see if anyone is interested in collecting a really special ginger.
