Do you know what type of ornamental ginger it is? Do the leaves look like a corn stalk? Are they are dull green or shinny green? Or are the leaves pleated? Do the leaves a a fragrant when crushed? Depends on what kind it is whether you can dig and store the rhizome. Or if the have a natually dormancy. You can send a photo I may could ID it for you.

I'm new to gingers; this is my first winter. Please tell me what you did last year and if it worked.

thanks
