Desmodium rosei, commonly known as Rose’s Ticktrefoil, is an annual herb native to open woodlands, forest edges, and grasslands in the Southwestern United States and Mexico. It typically grows to a height of 1.5-2 feet (0.5-0.7 meters) and a width of 0.3-0.5 feet (0.09-0.15 meters). This plant features trifoliate leaves and produces showy clusters of pink, purple, and white flowers during the summer and fall, which are attractive to pollinators such as bees and butterflies.

Rose’s Ticktrefoil is valued for its ornamental flowers and its ability to fix nitrogen in the soil, improving soil fertility. It is suitable for wildflower gardens, borders, and as a ground cover in restoration projects. It thrives in full sun to partial shade and prefers well-drained soils with moderate moisture. While it is generally low-maintenance, it can self-seed prolifically, which may be considered undesirable in some settings.CC BY-SA 4.0
