If the rain does not come, the water in the canal is being done in the valley. And the water begins to boil purple purple flowers.

The flowers are drawn to everyone. And it's a little more than the children's curiosity. In urban life, this flower is not quite visible in the village.

It is heard that, in the late nineteenth century, a tourists brought this plant from Brazil to the fascination of swampy swelling. It started spreading rapidly in rivers of Bangladesh. Then there was a disruption in navigation.

There are still hybrids in many places, especially in the bills and haors of the country, but they do not cause any problems in navigational or farming.

It is now mainly used as a fertilizer and during the monsoon, it provides food for livestock in flood prone areas. In addition to the haor areas, bamboos attached to the adjoining areas are used to protect the soil from the waves.

Many of the locals also call this flower togery.
