Cirsium Rivulare Atropurpureum - Brook Thistle
Spectacular, rich purple flowerheads appear on erect silver 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. Much loved by butterflies.
Grows to 120cm, spread 60cm
