What to Eat

Edible parts: Root, Stem

The root is edible cooked and is likely rich in inulin, a starch that humans cannot digest. It passes straight through the digestive system unchanged and may ferment in some individuals, producing flatulence. Young stems can be peeled and eaten raw; they are soft and sweet and are considered a luxury food. Young shoots, harvested in spring, can be eaten raw or cooked as greens. Seed oil can also be extracted by expression.

Where to Find It

It is a temperate plant. It grows in wet meadows and moist open woods.

Cirsium edule, the edible thistle or Indian thistle, is a species of thistle in the genus Cirsium, native to western North America from southeastern Alaska south through British Columbia to Washington and Oregon, and locally inland to Idaho. It is a larval host to the mylitta crescent and the painted lady. Cirsium edule is a tall herbaceous perennial plant, reaching 1–2 m (39–79 in) in height. The leaves are very spiny, lobed, 10–30 cm long and 2–5 cm broad (smaller on the upper part of the flower stem). The inflorescence is 3–4 cm diameter, purple, with numerous disc florets but no ray florets. The achenes are 4–5 mm long, with a downy pappus which assists in wind dispersal. It is monocarpic, growing as a low rosette of leaves for a number of years, then sending up the tall flowering stem in spring, with the plant dying after seed maturation. Edible thistle is used by Native Americans for its edible roots and young shoots. The roots are sweet, but contain inulin, which gives some people digestive problems. Varieties Cirsium edule var. edule - Oregon, Washington Cirsium edule var. macounii (Greene) D.J.Keil - Oregon, Washington, British Columbia, Alaska Cirsium edule var. edule wenatchense D.J.Keil - Washington
