Summary

Polygala verticillata, commonly known as Whorled Milkwort, is an annual herb native to a variety of habitats including prairies, open woodlands, and forest edges primarily in the Eastern USA. It typically grows to a height of 0.5-1 feet (0.2-0.3 meters) and a width of 0.5 feet (0.2 meters). This plant has a delicate appearance with narrow leaves arranged in whorls along the stem. The small, greenish to pink flowers bloom in the summer and fall and are not particularly showy, but they add a subtle charm to the plant’s overall aesthetic.

Whorled Milkwort is valued for its adaptability and can be used in wildflower gardens, as a ground cover, or for naturalized areas. It is relatively low maintenance, requiring medium amounts of water and thriving in full sun conditions. It prefers well-drained soils and can tolerate a range of soil types, making it a versatile choice for different garden settings. While not commonly used in formal garden designs, it is appreciated for its contribution to biodiversity and as a food source for pollinators. Potential problems include susceptibility to root rot in poorly drained soils.CC BY-SA 4.0
