What is "edraianthus"

Edraianthus (rock bells or grassy bells) is a small genus of flowering plants in the bellflower family Campanulaceae. Edraianthus species are native to mountains of the Balkan, including Croatia, Bosnia and Serbia, and as far as Romania, Italy and Greece.

They are small perennial plants, with tufts of grassy leaves and fine bell-shaped flowers, usually blue. They are often used as ornamental plants in rock gardens.

The genus name is derived from the Greek hedraios (sitting) and anthos (flower).
