Oxeye daisy was introduced to North America from Europe in the early 1800s as a grass seed contaminant. Later, it was cultivated as an ornamental plant and is still sold as a wildflower in many seed mixes.
Oxeye daisy has become a serious invader of pastures and natural areas throughout North America where it displaces desired vegetation. This plant is known to harbour crop diseases.
Flowers have yellow centers surrounded by white petals. Single flower heads grow on the end of un-branched stems and are 12-20 mm wide.
A key identifying characteristic of this species is that each plant has at least some oblong and spoon-shaped leaves with toothed edges.
Oxeye daisy stems grow 30-60 cm high and are typically hairless.
