Trollius × cultorum is a group of hybrid flowering plants of garden origin, belonging to the buttercup family Ranunculaceae. There are several cultivars, derived from T. europaeus, T. asiaticus and T. chinensis. These are clump-forming herbaceous perennials whose preferred location is heavy, moist or even boggy ground, in full sun or partial shade. Typically growing to 60 cm (24 in) tall, they bear showy double flowers up to 6 cm (2.4 in) in diameter. Flowers appear in shades of cream, yellow and orange. The curved "petals" are actually sepals, surrounding the smaller, nectar-bearing petals.

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
