This species of the wild iris is much larger and has spectacular large white flowers which are marked yellow and violet colours in the spring and summer. It can grow both in the sun and in partial shade. Similar to the Dietes Bicolor it is also tolerant of drought and frost, although it does need to be well watered in the summer.

Best for difficult parts of the garden, the rapidly spreading species grows to a height of 50cm and can cover the ground excellently. Their flowers are similar to the Dietes Grandiflora but much smaller. Again, similar to the other species it can grow in sun and partial shade. Although this flower cannot tolerate frost, lower temperatures can be tolerated if it is not a regular occurrence.
