Description
_clean,_no-description.jpg)
Unusually for a thistle, Cirsium heterophyllum lacks spines. Growing 45–120 cm (18–47 in) tall, the plant forms creeping stolons (runners). The stem is grooved but unwinged, more-or-less branchless, and cottony. The leaves are green and hairless above, thick white-felted underneath. The basal leaves are lanceolate with petioles and softly prickly edges, and grow 20–40 cm (7.9–15.7 in) long, and 4–8 cm (1.6–3.1 in) wide. The upper leaves do not have petioles, clasping the stem with cordate (heart-shaped) bases. The flower heads are 3 to 5 cm long and wide, the flowers red-purple, appearing from July to August.[3][4][5]

It is present throughout Scandinavia, in north central Europe and Russia to about 100 degrees East and in the high mountains of southern Europe. It grows in upland grassland and scrub, open woodland and river valleys.[4]: 695

The plant was considered a possible cure for sadness. Nicholas Culpepper in 1669 said that it "makes a man as merry as a cricket".[7]
