All the taxa within Cirsium fontinale have erect stems with leaves very strongly wavy margins.[2] These tall plants may attain a height of 2.2 metres (7.2 ft), but may exist in the form of only 0.5 metres (1.6 ft). A given plant may have one or more stems, and the plants are sometimes short-lived, dying after flowering only once, even though the species is acknowledged to be perennial. Lower leaves are typically petioled or tapered, but mostly spiny-lobed; petioles are either spiny-lobed or toothed.

Inflorescences are characterized by prickly heads more or less grouped in a panicle-like cluster, closely subtended by the higher leaves. Involucres are either hemispheric or bell-shaped, with purple to green coloration. Phyllaries range from a lanceolate to ovate shape. There are characteristically many flowers with white, pink or lavender corollae about 20 millimeters in length.
