Kola Bou: The Banana Tree Wife

Among Bengal's most distinctive Durga Puja customs is the tradition of Kola Bou — a banana plant, bathed, dressed in a red-bordered sari, and placed beside Shree Ganesh as his symbolic bride during the festival.

A Tender Family Exchange

The custom is remembered through a gentle household story: when young Ganesha asked his mother Durga why she seemed to eat so heartily, she teased that perhaps his own future wife would not feed her generously enough. Moved by this, Ganesha is remembered cutting a banana plant and presenting it to her, declaring it his bride — a promise that his mother would always be cared for.

Part of a Larger Ritual

Kola Bou is bathed in the Ganga or a local river each Saptami morning as part of the wider Nabapatrika ritual, in which nine sacred plants together represent the many forms of the Goddess, before being dressed and placed at Shree Ganesh's side for the remainder of the festival.

What Devotees Seek

Bengali families keeping this custom honor it as a tender expression of filial devotion — a reminder that a child's promise to always provide for a parent is itself a form of sacred offering.
