Did you know
- Unlike most St. John's wort species that prefer dry habitats, this one thrives with its roots submerged in shallow water.
- The woolly, soft-haired stems and leaves give the plant a distinctive grayish-green appearance unlike any other Hypericum.
- It spreads through creeping stems that root at the nodes, forming floating mats at the edges of ponds and bogs.
- The small yellow flowers have red-tipped glands along the petal edges that contain hypericin, the same compound found in medicinal St. John's wort.
- It is increasingly rare across Europe due to wetland drainage and is listed as a protected species in several countries.
