Green Ixia Family: Iridaceae Origin: South Africa Ixia viridiflora is a frost tender plant, thriving best in USDA plant hardiness zones 9-11. In cold climates, this small plant (2-5 feet in height) can be grown in a container and indoor during cold spells. For the container growing, use a potting mix that is well drained, as Ixia viridiflora is susceptible to root rot if overwatered. Plant the bulbs in autumn and they will form clumps that will remain in place for many years. During the growing season, give them enough water and fertilizer to sustain growth, particularly when the flower buds are developing. If the winter is too cold, or the bulbs are not well protected, they will not bloom the following summer. To protect the bulbs during winter, you must provide enough insulation like mulch or soil around the plants. When all the flowers have faded and the leaves have died down, the bulb can be lifted and dry stored in a dry and cool place before replanting in autumn. As one of the more unusual plants, Ixia viridiflora makes for a great addition to any garden.
