It is native to the Northern Hemisphere.[1] It grows in wetlands and along streams.[3]
In the UK, it has only been found to occur naturally in one location.[4][5] In 2025, efforts were made to establish it in the muddy waters of two reservoirs in Scotland, at Loch Coulter and Threipmuir Reservoir.[4][5]
