This species has been freely sown as a pasture and fodder plant throughout the state and has escaped frequently. No effort has been made to collect this species, Trifolium pratense or Trifolium repens; consequently the maps do not indicate the frequency with which they have escaped, but no doubt all are found frequently in every county.
