Perennial of the Campanulaceae family, native to the Caucasus and Transcaucasia, where it grows on grassy slopes, edges of clear forests, and high-altitude rocky areas, generally between 800 and 2,000 meters.
It forms upright and elegant clumps 20 to 40 cm in height, from a rhizomatous base. The basal leaves are oval-lanceolate, slightly crenate, of medium green, with the stem leaves becoming progressively sessile and narrower towards the top of the stems.
The flowers are the main asset of this species: large, hanging bells, of a deep and velvety purple-violet, borne in unilateral and arched clusters that give the plant a supple and graceful silhouette. The inside of the corolla is paler, creating a slight contrast with the strong exterior hue.
In its natural habitat, its flowering extends from June to August. In cultivation, it generally occurs in June-July.
It requires well-drained soil, moderately rich, in a sunny to semi-shaded exposure. Relatively little known in collections, it deserves a place in large rock gardens or borders, where the flexibility of its flowering stems can be fully expressed.
