Common names for Trollius laxus include American globeflower and American spreading globeflower. The American Globeflower, Trollius laxus is an endangered species of flowering plants Native to Northeastern United States. This species of plants is limited in range by their ability to exclusively survive in wetlands and marshes. Thus, clusters of the species are constantly threatened by the ever-changing hydrology of the range they are confined to.
Trollius laxus is a rare, herbaceous perennial only found in a small range of fens or wetland habitats fed by groundwater in northeastern United States. In these calcium rich fens, the T. laxus can be locally abundant. They can also be found in Oregon, Washington, British Columbia and the Rocky Mountains of Colorado. During spring, T. laxus is one of the first flowers to bloom in the Rocky Mountain. Its distribution is limited by light intensity and hydrology.
