Lysimachia europaea, commonly known as chickweed-wintergreen or arctic starflower, is a small herbaceous perennial native to coniferous and mixed forests, as well as boggy and marshy areas across northern Europe, Asia and western North America. It typically grows to about 4 inches tall and features whorls of pale green leaves that turn copper in late summer. The plant produces small, star-shaped white flowers with yellow centers in late spring to early summer, which are modest in appearance but add a delicate charm to woodland settings.

Chickweed-wintergreen is valued for its ability to thrive in shady, moist conditions, making it suitable for woodland gardens, shaded borders, and naturalized areas. It prefers consistently moist, humus-rich soils and can tolerate a range of light conditions from full shade to partial sunlight. While it is not known for aggressive growth, it can spread in favorable conditions and may become invasive outside its native range. Gardeners should be aware of its potential invasiveness and check local regulations before planting.CC BY-SA 4.0
