yes its a "real" ginger. Its a Hedychium (butterfly ginger).
Yes you can cut off the stalks that have already bloomed, they will never bloom again and will eventually brown and die back anyway, and yes, it will send up new shoots from the rhizome

Thanks so much. This plant is getting way too big. How close to the rhizome should I cut the stalks and should I dust it with a fungicide?

I always cut mine to within about 4 inches of the ground. As the cut stalk dries out, it will "release" from the rhizome and you can just pull it off. Fungicide is unnecessary.

To be honest I wouldn't do anything just at the moment, although this a vigorous plant, it's best to divide them after the weather gets warmer - esp in Maryland. Hope you have lots a friends as you'll be giving lots away !!

I wasn't thinking about dividing it, I just want to get it to a more manageable size. It's in my foyer and you have to fight your way through the plant to get into the house. I don't have anywhere else to put it that it won't be even more in the way until it can go back outside, besides that it seems to like this location. I was surprised that it's done as well as it has inside the house.

Hi Karyn,
Nice to see you on this board. Your ginger looked great. I never saw peach color ginger before. I couldn't help showing you my red/pink ginger plants that have grown in my Kauai place. I don't know how tall yours could get. These ginger was left without regular care. My place was left empty for a year and only mother nature has been good for them. I even brought a few roots along with, surely, many dozens of plumeria cuttings over to So Cal where I live.

Let me know if you'd like to trade yours with my ginger root, Daisy Wilcox or/and Scott Pratt cutting. Boom

Hi Boom. Those are beautiful. Did you weed the garden when you got there because it looks so clean. Is that a dormant plumie in the background? I'd kill for a vacation home in Hawaii! lol It might cost me a fortune to fly out there from the east coast. I've honestly never thought about dividing it and am not sure if it's big enough yet. I got the rhizome last summer. It was slow to get started but by the end of the summer it took off and continued after I brought it inside. It had the majority of it's blooms over the winter. I cut off a bunch of the stalks that had already bloomed last night and I'll take a look at the rhizome when I take it out in the spring. If it looks like it's big enough to divide I'd be happy to trade.

Hi Karyn,
That was an "After" picture.
Here is the "Before" picture. I took it the first day I got there;

The background was a dormant plumie alright. If you take a look at Plumie forum, you will see that ginger is the background.

If you'd like to trade, in spring would be great, I will try to root them which is even better.

This might be your ginger
