Onam is one of Kerala’s most loved festivals. It spans 10 days and marks the season of a bountiful harvest. People also believe that benevolent King Mahabali returns from the netherworld for one day to meet his subjects. They decorate pookkalams with fresh flowers and petals to welcome King Mahabali.
What is a Pookalam?
The word pookalam comes from the amalgamation of two Malayalam words:. ‘poo’, meaning flower, and kalam’, meaning a design or arrangement. People make colourful floral patterns at the entrance of homes, temples, and other spaces during Onam, called Pookkalam.
Did you know? Traditionally, the design will start small – with just 2-3 concentric layers. A fresh layer of flowers/petals adds to the design every day. The pattern becomes more elaborate as the festival progresses. They are beautiful, and making a pookalam is about togetherness, prosperity, and celebrating the spirit of Onam.

What flowers are used in Pookalam?
Different types of flowers (and sometimes, leaves) make up a pookalam. These come in different sizes, shapes, and colors. People pick flowers from their garden or source them locally for the design. The choice of flowers depends on tradition, availability, and region. People mostly pick wildflowers growing in the region for this purpose.
