Trollius laxus albiflorus

Trollius laxus albiflorus is a white-flowered variety of the American spreading globeflower, Trollius laxus. Globeflowers belong to the genus Trollius, which comprises about 20 species of perennial herbaceous plants in the buttercup family, Ranunculaceae. These plants are primarily found in wetlands of the North Temperate Zone.1

The common European globeflower (T. europaeus) is often cultivated in moist gardens and along pond edges, featuring yellow to orange, ball-shaped flowers. Typically, globeflower leaves are dark green to bronzy and divided into three to five lobes. The American spreading globeflower (T. laxus), native to eastern U.S. swamps, has greenish-yellow flowers, while T. laxus albiflorus is distinguished by its white flowers and is found in the northwestern United States.1
