Carlina acaulis (Stemless carline thistle, Dwarf carline thistle, or Silver thistle) is a perennial dicotyledonous flowering plant in the family Asteraceae, native to alpine regions of central and southern Europe. The common names are descriptive of the manner that its flower head rests directly upon a basal leaf rosette.

The spiny, pinnatilobate leaves grow in a basal rosette approximately 20 cm in diameter. The flowers are produced in a large (up to 10 cm) flowerhead of silvery-white ray florets around a central disc. The disc florets are tubular and yellow-brown in colour. The head closes in wet weather, a phenomenon which is held to presage forthcoming rain. The flowering time is between August and September.

It prefers chalky soils and dry pastures in environments from valleys up to an altitude of 2,800 m.

Subspecies
There are two subspecies:

Carlina acaulis subsp. acaulis – inflorescences sessile
Carlina acaulis subsp. simplex – inflorescences with a short stem


Uses
The rhizome contains a number of essential oils, in particular the antibacterial carlina oxide. The root was formerly employed in herbal medicine as a diuretic and cold remedy.

While young, the flowerhead bud can be cooked and eaten in a similar manner to the Globe artichoke, which earned it the nickname of hunter's bread.

It is sometimes cultivated as a rockery plant, or dried and hung as a house decoration.

Buna Cezar,
Fotografia asta mi-a amintit de copilaria mea, de zilele de vara cand ne jucam pe pajistile din Apuseni si ne feream sa nu calcam pe pernutele cu tepi.
Poza este super cu detalii foarte bune si o compozitie reusita.

Felicitari!

Mircea
