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. The spherical or cupped shape of the blooms gives rise to the common name globeflower, which they share with other Trollius species.
