Medicago falcata (Yellow Alfalfa) is a hardy, fast-growing perennial legume that produces cheerful yellow flowers and thrives in well-drained, even poor soils. As a nitrogen-fixing plant, it improves soil health over time and requires minimal fertilization. It is an excellent choice for wildflower meadows, erosion control, or as a pollinator-friendly ground cover.
