The marsh marigold is plant of the family Ranunculaceae found in wet areas in temperate regions of the Northern Hemisphere. Its striking yellow flowers have no petals but 4-9 (mostly 5) petal-like sepals and many yellow stamens. In Iceland it is one of the first flowers to bloom at the end of winter.
Marsh area along a river. Nesting ground for greylag geese. Þingvellir National Park, Iceland, a Unesco World Heritage Site. See the geese and more marsh marigolds at: http://www.projectnoah.org/spottings/368...
In Iceland this plant is found in the lowlands, but is sensitive to salinity. All parts of the mature plant are toxic. The toxin is protoanemonin (sometimes called anemonol or ranunculol), a toxin found in all plants of the buttercup family (Ranunculaceae).
