Leucanthemum
The Shasta daisy (Leucanthemum x superbum) is a commonly grown herbaceous perennial plant with the classic daisy appearance of white petals (ray florets) around a yellow disc, similar to the Oxeye daisy Leucanthemum vulgare Lam. but larger. Formerly classified in the genus Chrysanthemum, these daisies were transferred to their own genus of Leucanthemum because they lack some traits of true Chrysanthemums. Shasta daisies are characterized by a distinct odor which some find unpleasant, which makes them unusual amongst flowers.
The oxeye daisy (Leucanthemum vulgare, syn. Chrysanthemum leucanthemum), also known as the marguerite, is a widespread flowering plant native to Europe and the temperate regions of Asia. It is one of a number of plants to be called by the common name daisy. It is also sometimes called moon daisy or dog daisy
Leucanthemum paludosum (formerly Chrysanthemum paludosum and Mauranthemum paludosum) is a perennial plant of the Asteraceae family.
Leucanthemum maximum is a species of flowering plants in the aster family known by the common name max chrysanthemum. It is native to France and Spain but it can be found growing wild in other parts of the world as an introduced species and sometimes a garden escapee. It is a rhizomatous perennial herb growing 30 to 70 centimeters tall with many large serrated leaves around the base of the stem on winged petioles. There are smaller lance-shaped leaves alternately arranged along the stem. The inflorescence is generally a large, solitary flower head which may exceed 8 centimeters in diameter. It has a fringe of 20 to 30 white ray florets around a center of many densely packed yellow disc florets. The fruit is a small ribbed achene without a pappus.
This species is one of the wild chrysanthemums Luther Burbank crossed to produce the popular garden hybrid known as the Shasta daisy, Leucanthemum x superbum.
