White ginger is related to the edible ginger used in many Asian and Indonesian dishes, but is not edible---it's a showy tropical ornamental plant. This ginger grows from underground rhizomes that send up pale green, strap-like leaves that point upward to six feet tall. Its flowers are borne at the top of the plant and bloom in the summer months. Spring is the best time to start white ginger plants. If you live in a tropical or subtropical area, you can grow white ginger outdoors in rich soil in a partially shady location. Otherwise, grow it in a pot that you move indoors in fall.
Fill a large pot with a good quality, rich potting mix and then plant two to three rhizomes about two inches deep and two to three inches apart.
Keep your plant in an area that receives part sun and keep it moist, but not soggy.
Fertilize with a balanced fertilizer (10-10-10, for example) when you start to see growth appearing. To encourage flowering, use a low nitrogen or "blossom booster" fertilizer when the plant begins to send up a flower spike.
Cut flowers to enjoy in arrangements in your home. At the end of their blooming season, cut any remaining flowers back to soil level.
Create more plants by digging up and dividing the rhizomes during this ginger's dormant season.
