Eranthis hyemalis, also known as rooster or winter anemone, is a genus that has about ten species of deciduous, bulbous plants originating in Europe, Asia and the Mediterranean area. These are species that tend to fade quickly, constituting a real carpet; the leaves, in a basal rosette, are slightly leathery, dark green, glossy, finely divided. At the end of winter, starting from January-February, they produce thin, fleshy, erect stems, 10-15 cm high, on which bloom roundish flowers, similar to buttercups, which open on sunny days and close again at night and when the sky It is cloudy, presenting itself as small balloons; these flowers are golden yellow in color, and are subtended by leaves folded downwards, which take on the appearance of a collar. Bulbose very interesting also for the ease of cultivation, they are suitable as ground cover in rock gardens or in scrubland in large flowerbeds.
Place the winter anemone in a sunny or partially shady place; in fact, these plants do not like total shade. They do not fear the cold, but they may need shading during periods of extreme heat; in general we tend to place the bulbs of the eranthis hyemalis underneath high-trunk plants with deciduous leaves, so that in winter they enjoy a lot of sun and are shaded by new leaves in summer.
As for watering, the eranthis hyemalis are satisfied with the rains, but may need watering during flowering, in particular cases of very prolonged drought. In the autumn period, spread around the plants a slow release granular fertilizer.
These bulbous plants love loose, well-drained soils, rich in humus; It is important that the soil does not excessively retain moisture, to avoid favoring the rot of small bulbs. The eranthis settle down preferably in the months of August-September, buried about 7-10 cm; to favor the rapid development of roots it is advisable to soak the bulbs in lukewarm water for 10-12 hours before planting them. This facilitates their growth and allows them to enjoy the beauty of the plant longer.
The multiplication of the winter anemone or more of rooster, generally occurs by seed, in spring; small plants grow quickly, but you have to wait 2-3 years to get a satisfying flowering. It is also possible to divide the tufts that are formed with time, the portion taken is directly interceded into a dwelling.
The practice of pruning is not always a fundamental operation. In this case it is not necessary to prune the plant; it is sufficient to remove the damaged, dry or faded parts.
Fertilization must be carried out using organic fertilizers or granular products but only at the time of implantation. Later it is no longer necessary.
