Trifolium repens
In one study, chewing fescue or red fescue ("Festuca rubra") and ladino clover ("Trifolium repens") were effective living mulches for controlling weed growth. Unfortunately, these cover crops also competed with corn for water which was particularly problematic during a dry period. The possibility of using ladino clover ("Trifolium repens") as a potential living mulch was also mentioned; however, this clover was difficult to kill with herbicides in winter.
