Save to wishlist

Spectacular, deep crimson thistles appear on erect stems in July and August above spiny, dark green leaves.

This handsome, towering thistle is a valuable addition to a summer garden and looks equally at home in a wildflower meadow, beside water or in groups among other perennials.

Although Cirsium rivulare 'Atropurpureum' will tolerate dry conditions and partial shade, it does best in a moist, sunny border.

How to care for Cirsium rivulare Atropurpureum:

Cirsium thrives in moist, well-drained soil in full sun. Water well until established, especially in dry periods.

Cut back faded flower stems to encourage a second flush of blooms and prevent excessive self-seeding.

In autumn, trim plants to ground level to maintain a tidy appearance. Every few years, divide congested clumps between autumn and spring to rejuvenate growth and improve flowering.
