Common cooking ginger is a tropical plant that can be grown outdoors year-round in Zones 8-11, or in a container to bring indoors over winter. Ginger prefers moist soil and part shade. If you take the plant indoors over winter, reduce the amount of moisture and light to slow growth. You can start plants from gingerroot (actually rhizomes) sold in grocery stores. The plant has little ornamental value, so it's not often sold in nurseries.
