Growing

This rhizomatous perennial forms striking, sword-like fans of evergreen foliage that can grow into large, impressive clumps if left undisturbed for many years. Because it spreads via runners and rhizomes, it is an excellent choice for adding texture to your landscape, though you should keep an eye on its spread in garden beds. When you are ready to expand your collection, you can propagate the plant using seeds or by dividing the existing clumps.

To ensure your African Iris thrives, focus on drainage. This plant is susceptible to root rot if it sits in poorly draining soil, so a well-drained site is essential. If your garden naturally holds water, you might consider planting in raised beds to help keep the base of the plant above the moisture. Maintaining good weed control around the base of the foliage is also helpful for overall plant health.

As a hardy perennial, it is a wonderful addition to pollinator gardens, as the blooms attract various beneficial insects. Whether you are starting new plants indoors to transplant later or planting nursery stock directly into the ground, the plant will establish itself well in containers or garden borders. Once established, its low water needs make it a resilient choice for a variety of light conditions.
