Desmodium rotundifolium, commonly known as Round-Leaved Tick Trefoil, is a perennial herb native to the eastern United States, thriving in dry to mesic woodlands, clearings, and forest edges. It typically forms a low-growing mat with stems that can reach up to 2 feet in length, and it features distinctive round to heart-shaped leaves. The plant produces small, showy pink to purple flowers from late spring to late summer, which are attractive to pollinators such as bees and butterflies.

Round-Leaved Tick Trefoil is valued for its ability to fix nitrogen in the soil, enhancing soil fertility. It is often used in native plant gardens, restoration projects, and as a ground cover due to its low maintenance requirements. It prefers partial shade to full sun exposure and grows best in well-drained soils with moderate moisture. While it is not commonly afflicted by diseases, it can spread aggressively via seed and rhizomes, potentially becoming weedy in garden settings.CC BY-SA 4.0
