Cirsium rivulare ‘Atropurpureum’ is a striking perennial that brings strong vertical accents and rich colour to summer borders. Its deep crimson-purple, thistle-like flower heads rise on tall, elegant stems above clumps of soft green foliage, attracting bees and butterflies throughout the season. Despite its dramatic appearance, it’s a refined and well-behaved plant, not invasive like its wild cousins.
It thrives in full sun or light shade and prefers moist, well-drained soil.
