Dietes grandiflora
Fairy Iris
The Dietes grandiflora, commonly known as Fairy Iris, is a striking perennial plant valued for its elegant, white and purple irises that bloom profusely in spring and summer. The large, showy flowers are marked by delicate purple and yellow markings at the center, creating a beautiful contrast against its long, sword-like green foliage. Reaching a height of 60–90 cm and spreading up to 60 cm wide, it is perfect for borders, mass plantings, or as a low-maintenance groundcover.
Versatile and hardy, Fairy Iris thrives in a variety of conditions, making it an ideal choice for adding color and texture to garden beds, containers, or native plantings.
