Ox-eye daisy forms dense patches as it spreads by short rhizomes. Its crowded leaves hug the ground and as a perennial it continues to thrive year after year. Leaves are broadest at the tip, deeply notched and grooved, with a long narrow stem. They also give the appearance of being thick and leathery. Flowers are borne at the tips of long branching stems. They are typical of the daisy, with long white ray petals around the outside and bright yellow disc petals crowded in the center. Ox-eye daisy is a member of the large Composite family, which includes many turf weeds.
