Trollius × cultorum
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 tall, they bear showy double flowers up to in diameter. Flowers appear in shades of cream, yellow and orange. The curved “petals” are actually sepals, surrounding the smaller, nectar-bearing petals. The spherical or cupped shape of the blooms gives  rise to the common name globeflower, which they share with other "Trollius" species. The Latin specific epithet "cultorum" means “relating to gardens, cultivation”. "Trollius" × "cultorum" is an unresolved name, meaning that it has not yet been accepted as a correct botanical name or synonym. However, plants are widely offered in the horticultural trade. The cultivars ‘Superbus’ and ‘Orange Princess’ have gained the Royal Horticultural Society’s Award of Garden Merit. Other cultivars include ‘Alabaster’, ‘Lemon Queen’ and ‘New Moon’.
