The American Globeflower, Trollius laxus is an endangered species of flowering plants Native to Northeastern United States.

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.

Wetlands and marshes have consistent groundwater discharge which means that water levels will typically be high in these areas.

Trollius laxus is a perennial found predominantly in forested wetlands with cold alkaline groundwater.

This plant is one of the first to flower in the spring from mid-April to early May in Connecticut, and the seeds are ripened by mid-June where they are dispersed passively with the help of wind and water.

Removing neighboring plants lowers the predation risk on T. Laxus and increases its growth and reproductive success.

[6] Trollius laxus is easily identifiable by botanists due to their showy bright yellow flowers which are globular in shape.

The plant can include one or more stems, each with a cream or pale yellow flower up to 5 cm in diameter with 5-7 petaloid sepals.

The flowers of T. laxus range from white to yellow in color with nectar glands at the base, and can grow up to five centimeters in diameter.
