Common name: African daisy, Rain Daisy, Weather Prophet, Cape Marigold
Pretty aren’t they? Belongs to the sunflower family. The lower sides of the petals are supposed to be slightly mauve. Did not observe that. They are native to Namibia. And love sunny warm weather and are at their flowering best in the day time and face the sun, and so the face of the flower moves directions as the day progresses.
Seen in Lodhi Gardens, New Delhi.
