Red Clover, Cowgrass - Trifolium pratense


Family: Fabaceae Pea family Genus Common Name: Clover Native Status: Introduced
Trifolium pratense - Red Clover, Cowgrass. Red Clover is an introduced species which has become naturalized in every state in the United States and all but one Canadian province. While many species that have become so widely naturalized would be considered invasive, this plant has been welcomed due to its economic importance, even becoming the state flower of Vermont. The flowers, leaves and stem are edible, and are sowed for cattle fodder. Red Clover is also good for soil quality, being important in nitrogen fixation.
