Fortnight Lily or African Iris

Dietes bicolor (variously known as African iris or Fortnight lily) is a clump-forming rhizomatous perennial plant with long sword-like pale-green leaves, growing from multiple fans at the base of the clump. The blooms are yellow with three dark purple spots, each surrounded by an orange outline, and are followed by a capsule that may bend the flower stalks to the ground. Ripe seeds (dark brown in colour) are dispersed when the capsule dries and splits.
