I've never had my ginger flower but maybe in a longer growing season (than mine), it might - just have no idea. If you have only a small piece - maybe 1" - 2" - you may want to think about planting some more. I probably ended up with10 to 12 pieces (approx 1" - 1 1/2") so I have a little more harvesting flexibility. Yes, I can dig up a piece, take what I need and then replant if the piece is larger than I need. When I make my carrot ginger dressing, it requires at least 2 tbls per batch. I do have one large piece that I haven't touched in a couple of years and I'll be breaking that up into smaller sections to plant.
