About

Callitriche stagnalis is a perennial aquatic vascular plant species. Also known as pond water-starwort, C. stagnalis, may thrive in a variety of aquatic and subaquatic habitats, specially those exhibiting slowly moving to non-moving water. Although C. stagnalis does not pose a threat to humans, its reproductive rate may pose a threat to native vegetation in areas where it has been introduced, as the resulting dense vegetative mats frequently out-compete native species.

Where it grows

Callitriche stagnalis is normally found in aquatic environments particularly in which there is little to no motion. C. stagnalis frequents lakes, ponds, salt marshes, and slow moving rivers and streams. This species is able to thrive in both fresh and brackish water habitats.
