Perennial herbaceous plant native to the Mediterranean area, widespread as a wild plant also in our country; produces small rosettes of elongated oval leaves, light green; in spring from the center of the rosette thin stems rise, which bear a few leaves, at whose apex numerous bell-shaped flowers bloom, of blue-blue color; flowering continues until autumn; during these months the plant also produces new rosettes of leaves, which will flower the following year. It is often cultivated also as an annual, since it tends to self-seed easily and to produce new specimens every year. The leaves and flowers of campanula are edible, and are also used raw in salads. During the cold months the c. pyramidalis lose the aerial part, they will start to sprout again the following spring.
The bellflower pyramidalis are planted in a sunny or partially shady place; they are species that do not fear the cold and generally can withstand very harsh temperatures. In places with torrid summers it is advisable to place these campanulas in a place sheltered from direct sunlight during the hottest hours of the day to prevent leaves, buds and dried flowers.
The pyramidal bellflower species can withstand short periods of drought, but it is advisable to regularly water the plants to obtain an abundant development and a prolonged flowering in time. From March to October it is advisable and advisable to provide fertilizer for flowering plants, mixed with the water used for watering, every 15-20 days.
Our pyramidal bellflower plants prefer fresh and slightly humid, very well drained and quite rich soils. They adapt very well to any type of soil, and are often used in rock gardens or dry stone walls. They can also be cultivated in pots, remembering that the specimens grown in containers are slightly more demanding than those grown in the ground: they need more frequent care and very regular watering, to avoid that it dries the entire earthen bread contained in the pot.
The multiplication of c. pyramidalis occurs by seed, usually in late winter or autumn; during the autumn season it is also possible to divide the clumps of roots. We can propagate these perennials also by removing, in summer, the side rosettes to the main rosette, or by practicing basal cuttings in the spring period. The cutting is in fact a practice that makes it possible to reproduce the plant easily starting from a fragment of plant cut carefully and placed in the ground or in water to regenerate the missing parts.
Campanula pyramidal - Campanula pyramidalis: Pests and diseases
As for diseases and parasites, the pyramidal bellflower fears the attack of aphids and mites; the former, also called plant lice, ruin the flowers and young shoots. We can see the attack of the aphids if the leaves appear wilted and lymph-free. The red spider mites instead nestle on the underside of the leaves, bleaching them and making them fall down in advance. It is advisable to buy specific pesticide products to combat the problem.
