The carline with sheets of acanthus ( Carlina acanthifolia ) is a plant belonging to the kind Carlina and to the family of the Astéracées, or Made up. She flowers in summer and at the beginning of the autumn in mountain, generally in the dry meadows. The species includes/understands itself two subspecies:
- Carlina acanthifolia All. subsp. acanthifolia
- Carlina acanthifolia All. subsp. will cynara (Pourr. ex cd.) Arcang., also called carline artichoke .
Names of the plant
The generic name Carlina was borrowed from Italian. It is a probable alternative of cardina , derived from cardo (= thistle), the word being crossed with Carlo (= Charles) undoubtedly under the influence of a legend wanting that a angel showed with Charlemagne the species Carlina acaulis in presenting to him like a remedy against the Peste. the qualifiers acanthifolia and will cynara evoke one a resemblance to the sheets of Acanthe, the other with those of the Artichaut.
French vernacular names: Carline with sheets of acanthus (and carline artichoke ), barometer (or thistle barometer ), cardabelle, chardousse, pinchinelle .
German: Akanthusblättrige Eberwurz, Dornrose, Sonenrose, Wetterrosen . English: golden delicious thistle . Italian: carlina zolfina .
