Dimorphotheca pluvialis is an annual endemic to sandy and clay flats and slopes from Southern Namibia, Namaqualand and the Southern Cape.

During spring huge fields are covered with this bright white daisy, forming a dazzling mass. In their natural habitat the flowers are pollinated by small horseflies that get covered with pollen as they fly from one daisy to the next in search of tiny amounts of nectar.

These annuals are adapted to germinate, grow, flower and set seed during the rainy winter and to survive the long dry summer as seed. The seeds are interesting in that two different forms are produced. 

Flower season is between August and October. They are normally the first flowers to showcase their beauty after rain.
