In Bengal, Ganesha on Durga Puja is associated with a plantain (banana) tree, the "Kola Bou" (also spelled Kola-Bou), ritually transformed into a goddess during the festival.
On the first day of Durga Puja the Kola Bou is draped with a red-bordered white sari and vermilion is smeared on its leaves. She is then placed on a decorated pedestal and worshipped with flowers, sandalwood paste, and incense sticks. The Kola Bou is set on Ganesha's right side, along with other deities. For most who view her, the new sari indicates her role as a new bride, and many Bengalis see it as symbolizing the wife of Ganesha.
