Campanella, C. bianca - Leucojum


Leucojum is a genus consisting of about ten species of bulbous plants originating in Europe, Asia and North Africa. The round bulbs, with a diameter of about 5-7 cm, produce a stem 30-40 cm long, on which bloom some bell-shaped flowers, white and fragrant, with a bright green dot at the apex of each petal; they are very similar to snowdrops, but they have petals of identical length, while the snowdrops have three long petals and three short ones. The flowering time depends on the species: L. vernum blooms in late winter, like snowdrops; L. aestivum blooms in May; L. autumnale blooms in autumn, like L roseum. During flowering the bulb also produces leaves, ribbon-like, of a bright green color. THE Leucojum they are ground cover and the whole plant is poisonous. This plant is commonly known as a white bell because of the shape of its flowers.


For the development of white bell plants, the sunny or half-shade positions are certainly recommended, since the complete shadow prevents the development of flowers. In the hottest periods of the year they prefer mild temperatures and therefore there is a tendency to bury the leucojum at the feet of deciduous trees or shrubs. They do not fear the winter cold while the high temperatures of the summer season can undermine their health. They are plants that, if placed in the shade, have a poor flowering.


These bulbous plants fear the drying up during the vegetative period, therefore from March to May-June they need abundant watering; autumn flowering species need watering even in summer, while the others are in vegetative rest. In winter, avoid letting the soil dry completely. Obviously it is important to check that the soil allows good water drainage and prevents water stagnation, which is harmful to the health of these plants.


The white bell specimens prefer loose, well-drained soils rich in organic matter; use a compound consisting of peat, sand and mature organic fertilizer. Given the considerable need for water in the spring period, leucojums are often buried on the edges of ponds or ponds. To prepare a good substrate for these plants, it is possible to mix soil, sand, peat and organic fertilizer so as to have a light and rich compound, able to allow the best growth.


They propagate by removing in the autumn the bulbils naturally produced by the bulbs, then they are buried directly at home, without having to keep them in a protected environment for their taking root. They are plants of easy cultivation, which root quite quickly, without the need for particular precautions, even if it is better to use a rich and balanced substrate for planting.

Campanella, C. bianca - Leucojum: Pests and diseases

pay attention to powdery mildew and rust. The bulbs are very afraid of drying up during the vegetative period; if they are to be stored above ground it is good to keep them in damp peat. In the event that problems are noted it is advisable to proceed quickly with a specific treatment, because if the problem spreads, it is necessary to eliminate the affected specimens.
