In a Hindu wedding, especially in South India, at the entrance of the marriage venue a full-grown banana with their peduncles (stalk bearing banana fruit and flower) is erected. Ever wondered why it is erected? It is erected because Banana plant symbolizes female beauty, fertility and prosperity.
A single banana plant produces dozens of young ones. Thus, the plant symbolically represents fertility and prosperity.
Banana is also considered highly auspicious, as it is one fruit that is offered to all Hindu deities on all days.
