Cirsium arvense commonly known as creeping thistle is a perennial species of flowering plant in the family Asteraceae. The plant is native to southeastern Europe and the eastern Mediterranean area, and was probably introduced to North America. In addition to North America, Canada thistle is invasive in northern and southern Africa, the Middle East, Japan, India, New Zealand, Australia, and South America. The Standard English name in its native area is creeping thistle. Few of the popular common names of the plant are Creeping thistle, Field thistle, Californian thistle, Canadian thistle, lettuce from hell thistle, corn thistle, cursed thistle, field thistle, green thistle, hard thistle, perennial thistle, prickly thistle, small-flowered thistle, way thistle, Cardo cundidor, Choussio, Ciji, Da khawarak azghai, Honghuamiao, Ohtja, Koygocerten, Koygocuren, Ohakas, Perticone, Stioppone, Stramontano, stinger-needles, boar thistle, bull thistle, California thistle, Canada thistle, perennial creeping thistle and swamp thistle. In the past, C. arvense has been used beneficially as a medicinal and edible herb. The plant is beneficial for pollinators that depend on nectar.

Plant Description

Creeping thistle is a patch forming, herbaceous, rhizomatous creeping perennial plant that grows about 1 to 6.5 feet (0.3-2 m) tall. The plant is found growing in both disturbed (tilled) and no-tillage agricultural fields, arable land, roadsides, cultivated land, stream banks, ditches, lake shores, seashores, sand dunes, other open sandy areas, in clear cuts and forest openings, wet-mesic grasslands, prairie potholes, overgrazed pastures, meadows, fence rows, campgrounds, road building and pasture. The plant grows on all waterlogged, poorly aerated, and peat soils, including clay, clay loam, silt loam, sandy loam, sandy clay, sand dunes, gravel, limestone, and chalk. It also grows best on limestone soils with abundant moisture.

Root and Stem

The plant has a deep and wide-spreading root system with a slender taproot and far-creeping lateral roots. It often forms large patches, and individual clones may reach 115 feet (35 m) in diameter. Most Canada thistle roots are in the top 0.7 to 2 feet (0.2-0.6 m) of soil, but roots can extend as deep as 6.5 to 22 feet (2-6.75 m). Stems are 30–150 cm, slender green, and freely branched, smooth and glabrous (having no trichomes or glaucousness), mostly without spiny wings.

Leaves

Leaves are alternate on the stem with their base sessile and clasping or shortly decurrent. The leaves are very spiny, lobed, and up to 15–20 cm long and 2–3 cm broad (smaller on the upper part of the flower stem). They are dark green and lanceolate to oblong-lanceolate. They are glabrous above, but their undersides have short, white hairs. They may be pinnatifid and very prickly. Basal leaves are 5-8 in. (12-20 cm) long. Leaf characteristics are variable across different varieties and subspecies.

Flower

The inflorescence is 10–22 mm (0.39–0.87 in) in diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). The plants are polygamo-dioecious, thus there are male and female plants. The female inflorescences are flask-shaped, 1-1.5 cm (0.4-0.6 in.) in diameter, and 1-2 cm (0.4-0.75 in.) tall. The female flowers have a fragrance, while the male flowers do not. The male flowers are more globose in shape than the female flowers and are smaller. The flowers are usually purple in color, but can be pink or white. The plant is in bloom from June to August.

Fruit

The fruits (achenes) are tiny, 2-3 mm (0.1 in.) long and about 1 mm (0.04 in.) in diameter, and have a white to light brown pappus attached. Seeds are 4–5 mm long, with a feathery pappus which assists in wind dispersal. One to 5 flower heads occur per branch, with plants in very favorable conditions producing up to 100 heads per shoot. Each head contains an average of 100 florets. Average seed production per plant has been estimated at 1530. More seeds are produced when male and female plants are closer together, as flowers are primarily insect-pollinated.

Traditional uses and benefits of Creeping Thistle

Root is tonic, diuretic, astringent, anti-phlogistic and hepatic.
It has been chewed as a remedy for toothache.
Decoction of the roots has been used to treat worms in children.
