Biennial, sometimes short-lived perennial, from the Plantaginaceae family, native to Western and Central Europe, from the British Isles to the Iberian Peninsula and Morocco. It colonizes forest clearings, moors, embankments, shaded edges, and disturbed acidic soils, from sea level to over 1,500 meters in mountain massifs.
In the first year, it forms a large rosette of oval leaves, softly crinkled, covered with a grayish down on the underside, tender green on the upper side. In the second year, robust, erect stems rise from 80 to 150 cm, sometimes more, bearing a long unilateral spike of large thimble-shaped tubular flowers, pink-purple to pink-lilac, creamy white in some forms, with throats adorned with purple spots circled in white — a precise and repetitive pattern that guides pollinating bumblebees inside the tube.
In its natural habitat, flowering extends from June to August. In cultivation, it generally occurs from May to July depending on altitude and exposure.
An emblematic plant of European pharmacopoeia, it is at the origin of the discovery of cardiac glycosides in the 18th century by the English physician William Withering, who relied on a folk remedy to treat cardiac edema. The entire plant is highly toxic.
It self-seeds abundantly and is easily cultivated in fresh, acidic to neutral, well-drained soil, in partial shade or at the edge. It naturally integrates into woodland gardens and country-style compositions.
