Il diff\u00e8re de Tragopogon porrifolius car ce dernier poss\u00e8de des feuilles souvent ondul\u00e9es crisp\u00e9es. T. porrifolius a aussi des grandes ak\u00e8nes et des ligules anthocyan\u00e9es: pourpres.<\/p>\n\n\n\n

Il se distingue du tr\u00e8s proche Tragopogon pratensis<\/a> aux ligules \u00e9galement jaunes car son p\u00e9doncule est tr\u00e8s renfl\u00e9 sous le capitule, tr\u00e8s compressible.<\/p>\n\n\n\n

Il s’agit d’un salsifi! Racine et feuilles. Et bon courage pour l’\u00e9pluchage. Peut-\u00eatre ou sans doute moins savoureux que les vari\u00e9t\u00e9s de salsifis cultiv\u00e9es tout expr\u00e8s. V\u00e9rifier les statuts de raret\u00e9.<\/p>\n\n\n\n
