Oxeye daisy (Chrysanthemum luecanthemum) was introduced from Europe as a seed contaminant and as an ornamental. It is an erect, rhizomatous, creeping perennial that grows 10 inches to 2 feet tall. The basal and lower leaves are lance shaped and toothed with long petioles (leaf stem) and the upper leaves are narrower and clasp the stem. The leaf size progressively decreases up the stem. Flower heads are mostly solitary at the end of the flower stalk and the flower head has 15 to 30 white ray flowers.
