Dietes bicolor [Yellow Wild Iris, Peacock Flower, Evergreen Iris, African iris or Fortnight lily] is a plant with long sword-like green leaves. This species belongs to the Iridaceae [Iris] family.
The flowers are about 60 mm in diameter, flat, light yellow with brown markings and are produced on the ends of much branched flower stalks. The flowers only last for one day, but because so many buds are produced the plant is almost always in flower.
