Horticultural cultivar of the Spring Buttercup, a tuberous perennial from the Ranunculaceae family, distinguished by the warm, coppery tone of its flowers, unusual in the genus.
It forms small low clumps, 8 to 12 cm in height, with heart-shaped, glossy foliage, from glaucous green to grey-green, slightly fleshy, characteristic of the species.
The flowers are simple, with broad and rounded petals, in a warm yellow-orange hue tending towards coppery, with bright orange stamens that enhance the warmth of the whole. The natural gloss of the petals, typical of buttercups, gives them a particular shine in low-angle light. It is precisely this coppery hue that gives this cultivar its name, 'Cuprea' meaning coppery in Latin.
Its blooming in cultivation extends from February to April. Like all buttercups, the plant enters complete dormancy at the beginning of summer, disappearing completely until the following spring.
In cultivation, it prefers a fresh, humus-rich, and well-drained soil in summer, in partial shade or slightly sunny situation. It multiplies by division of the tubers at the end of the dormancy period.
