Campanula fragilis resembles the species. The species has been grown for generations. A 1907 edition of Gardening Illustrated said that the blue flowers are rarer than the white flowers. The species is sometimes mislabelled as
Campanula mollis in gardens. The difference between
Campanula mollis and this species is the shape of the leaves. Volume 6 of ''The American journal of horticulture and florist's companion'' said that the flowers are of a most lovely blue color and last a considerable long time. When potted, plants grow well in airy temperate conditions. Unlike most plants, the species is harmed by direct sunlight. It can only tolerate frost on the mountains of northern Italy, but pot-grown plants cannot. The authors Shane Smith and Marjorie C. Leggitt said that the species is best suited for a hanging basket. This plant has received the
Royal Horticultural Society's
