Cirsium kamtschaticum, the Kamchatka thistle, is an Alaskan and East Asian species of plants in the thistle tribe within the sunflower family. The species is found in eastern Russia (Kamchatka Peninsula,[2] Sakhalin Island and the Kuril Islands), and on certain islands of the North Pacific: the Aleutian Islands of Alaska and Hokkaido Island in northern Japan.[3][4]

Cirsium kamtschaticum is a biennial or perennial herb up to 200 cm (80 inches) tall, with a thick underground rhizome. Leaves are up to 40 cm (16 inches) long with thin, bristly spines along the edges. There are a few flower heads, each head with pink or purple disc florets but no ray florets.[3]
