My apologies for not getting back here sooner.
Thanks Greene for that interesting link. It certainly sounds like the plant I have.
I also appreciate the suggestion to contact Gingerwood Nursery ~ Jean.
Unfortunately my time doesn't look like it will free up any time soon and I hate to start the contact with them when I may not be able to follow through.
I would gladly share a division of this with you or anyone who may wish to pursue a more positive identity.
I will say, I was disappointed in the reputable online company that sold this as edible ginger. That single experience illustrates the internet as a resource can be "iffy" at best.
one and all...
