Water Stargrass:

Water Stargrass is so named for the star shaped flowers that rise above the water’s surface.  It has grass-like stems with thin branches.  These stems can grow up to six feet long and form floating colonies.  This aquatic plant reproduces through seeds and fragmentation.  Small pieces of stems can break off, lay dormant under mud, and then sprout in the spring.  The floating colonies provide an important habitat for macro and micro invertebrates.  These invertebrates an important in the food chain for fish, amphibians, and water fowl. 

Water Stargrass can grow in shallow water in streams, rivers, ponds, and lakes.  It can also grow in mud banks and in water with high salinity.  It can even grow on land if stems are washed ashore.  This plant can be controlled using Reward herbicide.
