Horticultural cultivar of the common snowdrop, a bulbous perennial of the Amaryllidaceae family, known and cultivated since at least the 17th century. It is distinguished from the type species by its fully double flower, of remarkable complexity: the three large external white tepals frame a center densely filled with additional floral parts, white and broadly marked with green, arranged in concentric whorls that evoke a small suspended miniature rose.
The plant reaches 10 to 15 cm in height. The foliage is identical to that of the type species: linear, glaucous, erect. The flower, heavier than that of the wild form, leans more on its slender stem, accentuating the characteristic drooping habit of snowdrops.
In its natural habitat, the flowering of the type species extends from January to March. This cultivar blooms at the same dates, generally from February to March in cultivation depending on the regions.
Sterile, it does not reproduce by seeds and propagates only by division of clumps after flowering, preferably still in leaves. It requires cool, humus-rich, well-drained soil, in partial shade under deciduous trees. Highly sought after by galanthophile collectors, it is among the oldest recorded double cultivars.
