📌 Product Description

Dietes bicolor, commonly known as African Iris or Fortnight Lily, is a hardy, evergreen perennial valued for its soft yellow flowers marked with dark brown and orange centres. The blooms appear in cycles, often every two weeks during the flowering season — giving rise to the name Fortnight Lily.

With its upright, sword-like foliage, this low-maintenance plant adds structure and movement to gardens. It is exceptionally well-suited to South African conditions and performs beautifully in borders, mass plantings, coastal gardens, and water-wise landscapes.
