I'm not sure about genticulata, but if yours has this powdery coating, maybe yours is dealbata.

You can grow the much like you would a canna. I grew mine in a large pot in a shallow area of my water garden when I was in Missouri. It will take water a few inches over the crown with no problem. Hope this helps!
