Campanula rumeliana - The bellflower clan (Campanulaceae) offers a wonderful blue splash of color throughout the summer. This rare species from the Balkans looks quite different from its cousins with spiky blue flower balls. Until recently, it was classed as Trachelium rumelianum—but DNA research has shown it to be a true blue bellflower, despite its strange looks. Find it in the Rock Alpine Garden.
