Dietes species
 

Dietes are spreading, strappy leaved plants native to South Africa. They belong to the Iris family, and produce an abundance of cream or white iris like flowers on long stems for most of the year. They grow extremely well in Australian conditions and have now become invasive in various regions throughout Western Australia.

 

HOW IT SPREADS

  • Dietes produce numerous seed pods which contain an abundance of seeds. Each seed can remain viable in the soil for an extended period of time and can readily germinate under most conditions.
