Leucanthemum vulgare

Leucanthemum vulgare, the ox-eye daisy or oxeye daisy, is a widespread flowering plant native to Europe and the temperate regions of Asia and an introduced plant to North America, Australia and New Zealand. It is one of a number of family Asteraceae plants to be called a "daisy", and has the additional vernacular names common daisy, dog daisy and moon daisy.
L. vulgare is a typical grassland perennial wildflower, growing in a variety of plant communities including meadows and fields, under scrub and open-canopy forests, and in disturbed areas.

Leucanthemum vulgare is a perennial herb one to three feet high by 1 foot (0.30 m) wide. The stem is mostly unbranched and sprouts laterally from a creeping rhizomatous rootstock.
The leaves are dark green on both sides. The basal and middle leaves are petiolate, obovate to spoon-shaped, and serrate to dentate. The upper leaves are shorter, sessile, and borne along the stem.

L. vulgare blooms from late spring to autumn. The small flower head, not larger than 5 centimetres (2.0 in), consists of about 20 white ray florets that surround a yellow disc, growing on the end of 1 to 3 ft (30 to 91 cm) tall stems. The plant produces an abundant number of flat seeds, without pappus, that remain viable in the soil for 2 to 3 years. It also spreads vegetatively by rhizomes.
