Leucanthemum × superbum, the Shasta daisy, is a commonly grown[1] flowering 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.

It originated as a hybrid produced in 1890 by the American horticulturist Luther Burbank from a number of daisies.

Some members of the genus are considered noxious weeds, but the Shasta daisy remains a favorite garden plant.

Many cultivars are suitable for cut flowers, such as 'Becky', 'Esther Read', 'Silberprinzesschen' (Silver Princess), 'Snow Lady', 'Tinkerbell', 'Wirral Pride', 'Wirral Supreme'.

Killin'[4] and 'Wirral Supreme' [5] have gained the Royal Horticultural Society's Award of Garden Merit.
