Scientific Name: Trifolium incarnatum
Crimson clover is a cool-season annual. It grows to a height of 12- to 20-inches. The leaf of crimson clover is about the size of red clover. It is light green in color and covered with soft hair. The trifoliolate leaves are usually unmarked but can sometimes contain a few dark-red spots. The plant generally has minimal branching. The flower is a showy crimson/burgundy flower. The flower head is approximately one inch in length and consists of 40 to 50 individual flowers. Crimson clover spreads by seed which is produced during the spring to early summer. Crimson clover is found throughout the Southeast.
Crimson clover is a winter annual which is used as a pasture forage crop. Crimson clover is also seeded along roadsides to be cut as forage, but the seeds can get distributed into non-forage areas. Mowing is the best cultural practice to prevent the establishment of crimson clover.
For optimum control, make your post-emergence herbicide application to crimson clover that is young and actively growing.
