Why is a banana tree dressed as a bride during Durga Puja?

During Durga Puja, a banana plant dressed in a white sari with a red border is worshipped as Kola Bou, meaning 'banana bride' in Bengali. The bridal appearance is rooted in Bengali cultural symbolism, in which a newly married woman is associated with auspiciousness. The tradition symbolises fertility, prosperity, and the importance of nature in sustaining life.
