Description EDIT
A clump-forming rhizomatous perennial plant with long sword-like pale-green leaves.
The adult plant is approximately 1m wide and 1m tall.
The flowers are yellow with three dark purple spots, each surrounded by an orange outline.
Growing EDIT
Fast growing, making it ideal for use in areas that need to be established rapidly.
Occurs naturally near streams and in marshy places, it is also drought resistant and frost hardy.

The plant spreads by means of its modified stems (rhizomes), which are located below the soil surface.

They thrive in damp situations and will tolerate light shade, but do better in full sun except in hot inland gardens where partial shade is best. For optimal results plant the yellow wild iris in soil containing plenty of compost and water regularly.

The plant is able to grow easily in very poor soil with little water and can be useful when plants need to be established on poor subsoils.

Dietes bicolor can be propagated by dividing the rhizomes of large clumps after the flowering period or in autumn. The seed of the plant germinates readily when sown in spring or autumn in a good, moist seedling medium.
Distribution EDIT
Found naturally in the Bathurst region of the Eastern Cape in South Africa.
Occurs naturally near streams and in marshy places.
History EDIT
Uses EDIT
Because the plant multiplies rapidly, it can be easily propagated for large scale plantings.
Its evergreen, spreading habit makes it suitable for use as a long lasting groundcover.

Often used in public gardens, beautification of commercial premises and along roadsides.

The flowers are not suitable for cut flower arrangements as they are so short lived.
