Clover, with its shamrock-shaped leaves and pollinator-attracting flowers, serves as a dense ground cover in lawns. Introduced to America in the 1600s, it gained popularity among farmers and homeowners, and now features in various grass seed mixes. Of the 300+ varieties, including yellow clover, the most common are white, red, and micro clover. Red clover is mainly used for hay, pasture, silage, and soil enhancement.
