Spanish daisy is a somewhat weedy but showy annual that abundantly produces perky yellow flowers. These contrast well with the attractive leaves, which are divided into narrow, linear segments. Plants are very easily grown from seeds in moist, but well drained, soil in a bright sunny spot. Its natural range is very wide range and includes most of the eastern and central United States, with introduced populations in California.
Another common name, bitterweed, alludes to the fact that it is unpalatable to grazing animals, a trait that accounts for its tendency to increase in poorly managed, overgrazed pastures and rangelands.
