Cirsium rivulare is a species of flowering plant in the family Asteraceae, native to eastern and western Europe, adventive in Britain, and naturalised in Sweden and Belgium.[1]
Growing to 1.5 m (4.9 ft) tall, this erect herbaceous perennial is a clump-forming thistle, with narrow grey-green prickly leaves and small purple globular flowerheads in early to midsummer.[2]
The Latin specific epithet rivulare means "brook loving".[3] The plant prefers moist conditions but can tolerate some dryness.
The cultivar Cirsium rivulare 'Atropurpureum', with deep crimson flowers, has received the Royal Horticultural Society's Award of Garden Merit.[4] It is very hardy down to at least −20 °C (−4 °F) (RHS rating H7), and thrives in full sun.
