What type of flowers did Koly ensure Hari had before leaving for the Ganges River?

Koly ensured that Hari had marigolds before leaving for the Ganges River because marigolds hold significant cultural and spiritual importance in Indian traditions. They are often associated with auspicious events and are commonly used in religious ceremonies and rituals. By giving Hari marigolds, Koly was reaffirming her connection to him and invoking the blessings traditionally associated with these vibrant flowers.

The other types of flowers listed don't carry the same cultural connotations within the context of the story. While roses, lilies, and daisies are beautiful in their own right, marigolds specifically symbolize protection and good fortune, making them a thoughtful choice in the narrative and reflective of Koly's feelings and intentions.
