Selected cultivar of Pulsatilla vulgaris Mill., a perennial from the Ranunculaceae family. It is a horticultural form resulting from the natural variability of the species, which spontaneously produces individuals with white flowers in certain wild populations of Western and Central Europe.
The habit and foliage are identical to those of the type species. The clump reaches 15 to 30 cm at flowering, with finely divided foliage in narrow segments, a bright green, which fully develops after the flowers. The stems and bracts retain the same characteristic silvery silky pubescence of the genus.
The flowers with six tepals are pure white to slightly creamy at the bud stage, then open into a flared cup to reveal a dense center of bright yellow stamens, particularly luminous in contrast with the whiteness of the tepals. The still-closed bud, visible in some shots, shows a characteristic ivory hue before full bloom.
In cultivation, flowering occurs from March to April. It requires a well-drained soil, preferably calcareous, in full exposure.
