The Oxeye Daisy (Leucanthemum vulgare); also known as the Common Daisy, Field Daisy, Dog Daisy, Moon Daisy and Marguerite; is a perennial herb/forb in the Asteraceae (Aster) family and order, Asterales. The order and family names come from the Greek for "morning star." The genus name is from the Greek for "white flower." The species name is from the Latin for "common." This plant can grow to a height of three feet (91 centimeters). It flowers from June to August.

The flower heads are up to about  two inches (5.08 centimeters) in diameter. Each head will have from 15 to 35 white, female ray flowers surrounding yellow disk flowers that are both male and female. The yellow disk is up to ¾ inch (1.9 centimeters) in diameter and depressed in the center.

Oxeye Daisy (Leucanthemum vulgare) Leaves

The leaves of the Ox-eye Daisy are dark green, arranged alternately on the stem, deeply lobed and up to six inches (15 centimeters) long. The leaves become shorter as they are higher on the stem.

The fruit is a cylindrical, brown-stripped, yellow seed about 0.06 inches (1.5 millimeters) long. The seeds remain viable for up to three years.

The root system is a rhizome. This plant will propagate by seed or creeping rhizomes.

The Ox-eye Daisy is very invasive and the milk of cows that eat this plant will have an offensive taste. Many states consider this plant so noxious that it must be destroyed. However, its elimination is very difficult because the seeds and rhizomes are very hardy.

This plant may cause contact dermatitis in some people. The unopened buds are sometimes marinated and eaten like capers.
