About African iris
Dietes grandiflora, commonly known as the African iris or fairy iris, is a rhizomatous perennial plant that produces elegant white flowers with yellow and purple markings. Its sword-like foliage forms dense clumps, making it an excellent choice for borders, flower beds, or as an accent plant in Mediterranean or xeriscape gardens.

Care tips
This species thrives in full sun to partial shade, preferring at least 6 hours of direct sunlight for optimal blooming. It is drought-tolerant once established but benefits from regular watering during dry periods, allowing the soil to dry out slightly between waterings. Use a well-draining soil mix; the common mistake to avoid is overwatering, which can lead to root rot.
