Medicago polymorpha
Medicago polymorpha, commonly known as bur clover, is a species of flowering plant in the legume family Fabaceae. It is native to the Mediterranean region but has spread to various parts of the world, including California and other areas with a similar climate. This plant is characterized by its clover-like leaves and small yellow flowers, which bloom in clusters. It typically grows as a low, spreading ground cover.
Bur clover is often found in disturbed areas, grasslands, and pastures. It is valued for its ability to fix nitrogen in the soil, improving soil fertility. Additionally, it serves as forage for livestock and can be used in erosion control due to its dense growth habit.
