Brook Thistle

Cirsium rivulare Atropurpureum

• Position: full sun
• Soil: moist, well-drained
• Rate of growth: average to fast-growing
• Flowering period: July and August
• Hardiness: fully hardy
  
  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 it will tolerate dry conditions and partial shade, it does best in a moist, sunny border.
  
  
• Garden care: Divide congested plants from autumn to spring and cut back to the ground in autumn to prevent self-seeding.
