Lysimachia nummularia, commonly known as moneywort or creeping jenny, is a perennial flowering plant native to Europe and parts of Asia. It features small, round leaves and produces bright yellow flowers in late spring to early summer. This plant typically grows in moist, well-drained soils and can thrive in both sun and partial shade. Creeping jenny is often used in gardens for ground cover due to its ability to spread quickly and its attractive foliage. It is also valued for its ornamental qualities, as the leaves can turn golden-yellow in the fall, adding vibrant color to landscapes.
