Leucanthemum × superbum [or 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. 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.
It originated as a hybrid produced in 1890 by the American horticulturist Luther Burbank, Leucanthemum lacustre [Brot.] Samp. × Leucanthemum maximum [Ramond] DC. 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 and groundcover.
