Leucanthemum × superbum, the Shasta daisy, is a commonly grown[1] flowering herbaceousperennial 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 (Ramond) DC.; this double hybrid was itself crossed with (Brot.) Samp.[2][3] The resulting Leucanthemum triple hybrid was crossed with Nipponanthemum nipponicum (Franch. ex Maxim.) Kitam., 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.
