Annual, nitrogen-fixing cover crop that is well-suited to dry, rocky, or infertile soils. Introduced from Turkey, it has become a common pasture plant in California. Rose clover will take more heat than Crimson Clover, and is usually lower-growing. For pastures and vineyards, it is usually sown in early fall to overwinter with natural rainfall. In irrigated situations where it will get some water and shade, it can be used as an understory plant all season.
