Common fleabane is a yellow daisy with gray-green felty leaves and stems. When it blossoms, it spreads a soap-like odor. In earlier times, people used this scented flower for driving off insects (fleas), which explains its English name. Common fleabane also helped in preventing dysentery and the leaves for healing bruises and wounds. Cows avoid eating the plant. Therefore, common fleabane easily spreads when grazing is extensive. Too many grazers result in trampling. This plant is an important source of pollen for wild bees.
