Grow African iris as an annual in Zones 7 and below. Enjoy the bright white blooms in container gardens or planting beds for the season and replant the following year. You can overwinter African iris rhizomes by digging them up before the first fall frost. Allow the rhizomes to dry in a cool, dry place for about a week before packing them in peat moss for storage over winter. Replant in the spring when the soil warms.
