Leucanthemum × superbum
Template:Short description Template:Italic title Template:Speciesbox Template:Stereo image
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. First, he crossed Leucanthemum vulgare with Leucanthemum maximum; this double hybrid was itself crossed with Leucanthemum lacustre.[2][3] The resulting Leucanthemum triple hybrid was crossed with Nipponanthemum nipponicum, creating an intergeneric cross of species from three continents.[2][3] It was named after Mount Shasta, because its petals were the color of the snow. 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' (Template:Tdes), 'Snow Lady', 'Tinkerbell', 'Wirral Pride', 'Wirral Supreme'. The cultivars 'T.E. Killin'[4] and 'Wirral Supreme' [5] have gained the Royal Horticultural Society's Award of Garden Merit.[6]
