The Carniolan Primrose (Primula carniolica) has bishop’s red, pink flowers and delicate, shiny green leaves, which are not powdery like those of the Bear’s Ear. It was already known to the naturalists I. A. Scopoli and F. X. Wulfen, but they did not consider it a new species. It was only described by the Viennese botanist N. J. Jacquin. It was sent to him by B. Hacquet, who incorrectly stated that it grows in the Carniolan Alps, which is not true, as it is not found in the Alps. Of all the primroses that grow in Slovenia, it is the most native to our country, as it is not found outside its borders. It is one of the most beautiful younger (progressive) endemics, its range is very narrow. It grows in moist and shady gorges on the northern outskirts of the Dinaric Alps and south of Ljubljana. Its most famous locations are in the Trnovski gozd, around Idrija, Trebuša and Cerkno, in Dolenjska near Ribnica and Sodražica, in Notranjska near Cerknica, around Ljubljana and Iški Vintgar, Iška, Borovniški Pekel and on Zaplana. In Gorenjska, it grows in Sovre above the Žiri valley. The Carniolan primrose is protected, and classified in the Red List as a non-threatened plant.

In Jelenek near Idrija and on the northern slopes of the Trnovski gozd, where the Bear’s Ear and the Carniolan Primrose grow together, hybrids were found, which they called the graceful or Idrija Primrose (Primula x venusta).
