I was given my first ginger this spring. It looked awful. It had 2 or 3 little stalks that were about 4 or 5 inches long. I planted in a moist area and it just started growing like crazy. It is now about 15 to 20 stalks and they are about 2 and a half feet tall. I love the look of it and am going to have to over winter inside, but why has it not bloomed? any advice would be great.
