Yeah, some of us have no clue. One DGer - can't remember who or what thread - said that one of the gingers she and I both have is one she called "Hidden Ginger" because the flower was hidden. That doesn't appeal to me because if they are going to have a pretty flower (and it was) I want to be able to see it. Otherwise, I see no reason to have gingers or any flower that is so hidden you can't enjoy it so the gingers may have to go in favor of something a little prettier. Thanks for the input. I appreciate it.
Ann I'm in zone 8a and almost exclusively grow hedychium gingers. They do die back to the ground here in the winter, I pull the dead canes right off the rhizome in the spring. Easy cleanup. I could cut them back in the fall but I'm a lazy gardner and I let mother nature do all the work for me.
Many of them go dormant but I don't know if they 'all' go dormant.
I wonder if there are any kinds that don't ever go dormant?
Also if dormancy is triggered by daylength or by temperature? I guess I need to do more homework lol.
