Summary

Lysimachia quadrifolia, commonly known as Whorled Yellow Loosestrife, is a deciduous herbaceos perennial native to moist woodland areas, forest clearings, and along stream banks in the Eastern United States and Canada. This species typically grows to a height of about 1 meter (3.3 ft) with unbranched stems and whorled leaves that give it its common name. The flowers, which bloom from June to August, are star-shaped, bright yellow with a reddish center, and sometimes reddish margins, and are quite showy due to their contrast against the green foliage.

Whorled Yellow Loosestrife is valued for its attractive flowers and its ability to thrive in a variety of soil conditions, although it prefers moist, well-drained soils. It is used in garden borders, wildflower gardens, and as a ground cover in shady areas. It requires medium amounts of water and can tolerate full sun to part shade. While not aggressive, it can spread in favorable conditions, so gardeners should monitor its growth. It is relatively free of serious pests and diseases, making it a low-maintenance addition to the garden.CC BY-SA 4.0
