Isoëtes lacustris
Also called Lake quillwort, Common Quillwort, Quillwort, Deepwater Quillwort, Large Spored Quillwort, Isoète Lacustre, Merlin's Grass
Isoetes lacustris is a boreal quillwort, a grass-like aquatic fern ally, that grows submerged in cold, clear, nutrient-poor lakes in northern Europe. It is a wild species rather than a garden plant, and it needs cold, clear, oligotrophic water to survive.
Isoetes lacustris, the lake quillwort or Merlin's grass, is a boreal quillwort native on both sides of the northern Atlantic Ocean. In Europe, it is distributed from Poland west to northeastern France, throughout Scandinavia, the west and north of the British Isles, the Faroe Islands and Iceland. Further south, isolated populations occur in the glacial lakes of the Pirin mountain range in Bulgaria.
