Lysimachia latifolia, commonly known as Pacific starflower, is a low-growing, creeping perennial herb native to the understory of coniferous forests and mixed woodlands in the Pacific Northwest of North America. It typically reaches heights of 4-8 inches (10-20 cm) and spreads via rhizomes to form a dense ground cover. The plant features dark green, lanceolate leaves arranged in a whorl around the stem, and it produces star-shaped white or occasionally pink flowers from late spring into early summer (April or May), which are modest in size but can be quite numerous.

Pacific starflower is valued for its ability to thrive in shady, moist conditions, making it an excellent choice for woodland gardens, shaded borders, and naturalized areas. It is also appreciated for its evergreen foliage in mild climates, providing year-round ground cover. In cultivation, it prefers cool, moist, well-drained soils and can tolerate a range of light conditions from full shade to partial sun. While generally low-maintenance, it can spread aggressively in favorable conditions, so gardeners should monitor its growth to prevent unwanted spread. It has no major pest or disease problems, but its invasive potential should be considered before planting outside its native range.CC BY-SA 4.0
