Appearance
Unusually for a thistle, ''Cirsium heterophyllum'' lacks spines. Growing 45–120 cm tall, the plant forms creeping stolons . 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 long, and 4–8 cm wide. The upper leaves do not have petioles, clasping the stem with cordate bases. The flower heads are 3 to 5 cm long and wide, the flowers red-purple, appearing from July to August.
