These are bright yellow and orange flowers belonging to the Sunflower family. They look similar to the Marigold flower – the most popular flower this season in India adorning doorways and garlands.
Pot marigolds are said to bloom at the beginning of the month and thus got its name from Kalendae, Latin for first day of the month. The petals of the flower are known to have medicinal properties.
