What is the common name for Leucanthemum vulgare?

The common name for Leucanthemum vulgare is oxeye daisy.

Oxeye daisy is a perennial herb in the sunflower family, Asteraceae. Its familiar flowerhead has a yellow centre made of many tiny disc florets, surrounded by white ray florets that look like petals. The plant is native to Europe and parts of temperate western Asia, but it has been introduced and naturalised in many other regions.

The scientific name has changed in botanical history: Jean-Baptiste Lamarck formally described the species in 1778, and it was once placed in the genus Chrysanthemum. The species is also called dog daisy, field daisy, moon daisy, marguerite and white daisy, but oxeye daisy is the standard common name expected here.

It is easy to confuse oxeye daisy with the common daisy, Bellis perennis, or the cultivated Shasta daisy, Leucanthemum × superbum. Shasta daisies are hybrids with generally larger flowerheads. Oxeye daisy can also become an invasive weed because underground rhizomes help it form dense colonies and regenerate from fragments.
