A bee feasting on a Shasta daisy, Leucanthemum × superbum. The Shasta daisy, is a commonly grown 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. The resulting Leucanthemum triple hybrid was crossed with Nipponanthemum nipponicum, creating an intergeneric cross of species from three continents.
It was named after Mount Shasta, because its petals were the colour of the snow. Some members of the genus are considered noxious weeds, but the Shasta daisy remains a favourite garden plant.
