Leucanthemum is a genus of flowering plants that belongs to the family Asteraceae. They are commonly known as "daisies" or "oxeye daisies" and are prized for their white, yellow, or pink blooms. Leucanthemum plants are native to Europe, Asia, and North America, and are now grown in many other parts of the world as ornamental plants.

Leucanthemum plants have upright stems that can reach up to three feet in height. The flowers are typically white with yellow centers, although some species have pink or yellow petals. The foliage of Leucanthemum plants is often green and slightly hairy, and can be quite narrow and pointed.
