Tofieldia Calyculata

Greenish-yellow flowers, grouped in a dense spike, are mounted on a straight and stiff stem, and open from June to August on the high mountains of Gotland, Estonia southward to the Pyrenees, Montenegro and the Ukraine, where they live in swamps and wet grasslands. These unusual plants used to be variously in the gentian and lily family, but now reside in the Tofieldiaceae!
