Perennial of the Campanulaceae family, native to Turkey, where it grows in rock crevices, cliffs, and rocky screes, mainly on calcareous substrate, between 1,000 and 2,500 meters altitude.
It forms small low and creeping tufts, 5 to 15 cm in height, with thin and diffuse stems that spread between the stones. The leaves are small, oval to elliptical, slightly toothed, medium green, borne on slender and branched stems that resemble those of Asperula, as reflected in its specific epithet.
The flowers are tubular to slightly flared, blue-violet to pale lilac, borne individually or in small groups at the end of the branches. Their modest size matches the small and delicate character of the entire plant.
In its natural habitat, its flowering extends from June to August. In cultivation, it generally blooms in June-July. It requires a very well-drained, mineral soil, preferably calcareous, in a sunny exposure. Its creeping nature and fine habit make it an interesting candidate for wall crevices, flat rock gardens, and collection troughs in alpine houses, where it can thrive sheltered from excessive winter moisture.
