Crimson clover is an easy-growing annual or short-lived perennial that thrives in average garden soil with moderate moisture and partial sun. It is widely used as a cover crop to fix nitrogen and improve soil fertility, making it excellent for vegetable garden rotations. Sow seeds directly in the garden and enjoy its vivid scarlet flower spikes that attract bees and pollinators.
