It is a Eurasian blue wildflower native to Denmark and England and now naturalized in southeast Ireland.

[2] Other folknames include Our Lady's Bells because the color blue was identified with the Virgin Mary's scarf, veil, or shawl; Coventry Bells because C. trachelium was especially common in fields around Coventry; and "Bats-in-the-Belfry" or in the singular "Bat-in-the-Belfry", because the stamens inside the flower were like bats hanging in the bell of a church steeple.

[3] Campanula trachelium is a perennial plant with one or more unbranched, often reddish, square-edged stems that are roughly hairy.

The upper leaves have no stalks and are ovate or lanceolate, hairy with toothed margins.

[4] Campanula trachelium likes humus-rich soil and is found in broad-leaved woodlands, coppices, hedgerows and the margins of forests.
