About

Lysimachia borealis (synonym Trientalis borealis), the starflower, is a North American woodland perennial that blooms between May and June.

Where it grows

Lysimachia borealis is found from Canada to north-central and eastern United States, primarily in boreal forest in Canada and in northern conifer-hardwood forests in the United States. It is found in temperate climates. The species is one of the ten most common herbaceous-layer native plants in eastern deciduous U.S. National Park forests. Lysimachia latifolia (Pacific Starflower), which is a pinkish, purple variety, is native to the west coast of the United States and parts of western Canada.
