Appearance

The blooms are white marked with yellow and violet. Dark markings are found at the base of the outer tepals. These are borne in abundance during summer, especially after rain.

Dietes grandiflora Native to eastern and southern South Africa, this plant does very well here in Australia with its similar environs and weather... it is regarded as an environmental weed in Western Australia and as a potential environmental weed here in New South Wales. 

It is a rhizomatous, evergreen perennial producing large iris-like flowers at the ends of tall, thin stalks. Leaves are upright, stiff and sword-like.
