Carlina

The genus Thorn (Carlina) includes various (about 20) herbaceous perennial resistant plant species. Under natural conditions, they are found in arid areas characterized by a low amount of precipitation, on limestones among rocks and rocks, in dry meadows, pastures and forests in high-and medium-mountain regions, and less often in valleys. The flowers are similar in appearance to the flowers of the villi, collected in baskets, kept on the plant for a long time. The prickly thorn (Carlina acanthifolia) is widespread everywhere, a plant up to 60 cm tall, with prickly leaves collected in basal rosettes and large (up to 15 cm) baskets with purple flower corollas. They are grown most often in stony gardens. Stalk-less thorn (C. acaulis) is a mountain species. Baskets with white marginal scales, reaching 13 cm in diameter, consist of white or reddish flowers. Prickly leaves form rosettes, and in taller (above 40 cm) plants, contrary to their name (Lat. - without a stem), they are distributed along the flower-bearing shoot.

Cultivation

These are typical plants for decorating stony gardens, only seedlings are grown in pots. Their requirements are minimal. It is only important to ensure good soil drainage. Ideally, if the soil surface is rocky or rocky.

Location

The best location is undoubtedly in the open sun. Thornless also tolerates partial shade well.

Temperature

These plants are resistant to both high and low temperatures.

Watering

No special watering is required; rain is sufficient. Water only seedlings in pots.

Reproduction

Sow in open ground in autumn or spring in well-drained soil. In addition, they are propagated by dividing plants in autumn, after which separate parts of the plant are placed in sawdust or wet peat, and in spring they are finally planted.

Diseases

Rotting is the only problem when growing this plant. The root system rotts if the crop is planted in too dense and water-tight ground. Be careful: plant in a loose substrate and avoid the possibility of stagnation of water.

Acquisition

This is a fairly rare plant, so seeds should be ordered in advance.
