Cirsium rivulare ‘Atropurpureum’ is an ornamental thistle, bearing incredible, deep purple thistles on elegant, long, leafless stems, in contrast with spiny, dark green foliage. It’s a wonderful choice for growing towards the back of a sunny herbaceous border, and works well when planted among grasses and other tall perennials.
Grow Cirsium rivulare ‘Atropurpureum’ in moist but well-drained soil, in full sun. Cut plants back in autumn to prevent them self-seeding, or leave them intact to provide a winter source of food for birds. Lift and divide congested clumps in autumn or spring.
