Campanula trachelium

Perennial herb with latex.

40–100 cm high.

The stem is erect, simple, acutely angular, hispid and often reddish.

The petiole is at most narrowly alate. The size of the lamina is 4–10 cm x 2–8 cm. The lamina is double-serrate and hirsute. The proximal leaves are typically long petiolate, cordate – ovate. The distal leaves are sessile and ovate or ovate-lanceolate.

The inflorescence is often an interrupted terminal raceme that consists of one-to-four-flowered cymes. The lowest bracts are similar to the cauline leaves and distinctly longer than the flowers. The flowers are initially erect and eventually slightly drooping. The length of the calyx lobes is 1/3 – 1/2 of the length of the corolla, and the lobes are ovate-deltoid, over 2 mm wide and erect. The corolla (25–45 mm) is purple.

The poricidal capsule is drooping and dehisces at its base.
