This plant is found in wet lands and is a problem in lakes like Fewa tal, Begnas etc. These invasive species can grow upto 1m and can double its population in two weeks. The flower is purple with light pink petals and thick 10-20cm ovate leaves.  Every year a lot of resource is used to clean up the lake as travelling through it becomes difficult and also degrades the water quality.
