It sometimes will function as an annual, flowering in the first year. The biology and non-chemical control Spear Thistle (, Defra, UK - Farming - Wildlife and plants. [2][12][13], Spear thistle is often a ruderal species, colonising bare disturbed ground, but also persists well on heavily grazed land as it is unpalatable to most grazing animals. Altervista Flora Italiana, Cardo asinino. Some species in particular are cultivated in gardens and wildflower plantings for their aesthetic value and/or to support pollinators such as butterflies. [16] The seeds are dispersed by wind, mud, water, and possibly also by ants; they do not show significant long-term dormancy, most germinating soon after dispersal and only a few lasting up to four years in the soil seed bank.
It is a biennial herb that is native to Europe. The inflorescence is 2.5–5 cm diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). Il cardo asinino (nome scientifico Cirsium vulgare (Savi) Tenore 1835 - 1838) è una pianta erbacea biennale, abbastanza robusta e caratteristicamente spinosa, appartenente alla famiglia delle Asteraceae Foliage It is best cleared from land by hoeing and deep cutting of the taproot before seeds mature; regular cultivation also prevents its establishment.[13]. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. [14] The flowers are a rich nectar source used by numerous pollinating insects, including honey bees, wool-carder bees, and many butterflies. [7][8][9] It is the national flower of Scotland. Cirsium vulgare is an annual or biennial, herbaceous plant that invades disturbed areas throughout the United States.
It is the national flower of Scotland. [15] The seeds are eaten by goldfinches, linnets and greenfinches. This herb grows in fields and roadsides, and it can (2007).

[10] Marsh thistle, Cirsium palustre, was ranked in first place while this thistle was ranked in sixth place. [23] The dried florets steeped in water are used in rural Italy for curdling goats' milk in preparation for making cheese.

[13] Nitrogen-rich soils help increase its proliferation. NATURALIZED Habit: Biennial 3--20 dm. アザミ属の花は虫媒花で、花粉と蜜によって虫を誘う。頭状花序（花）は多数の筒状花からなり、多くの種で、一つの筒状花は中心に細長く伸びるめしべとそれを筒状にすっぽり包むおしべを備える。虫が花に止まるとおしべがひっこんでめしべと擦れ、花粉が外にかき出される[1]。しかし一部には、両性を備えた個体と、おしべに花粉がない、つまり実質的に雌花である個体との、2つの型を持つ。さらに一部には、雌花だけを作る草と、雄花だけを作る草に分かれる雌雄異株の種がある[2]。花の色は主に紫色である。, 北半球の温帯から寒帯に分布する。紫系の丸い花、切れ込みととげのある葉といった特徴を共有しつつ、活発に種分化し、北アメリカに約90種、ヨーロッパに約60種、中国約50種、日本にも60種以上、全部で約300種ある[3]。日本産のアザミは4種を除き日本特産である[3]。分布域が比較的広いものと極端に狭い地域固有種がある。鳥海山だけのチョウカイアザミ、白馬岳だけのダイニチアザミといったごく狭く分布する種も少なくない。分布が接する地域では容易に種間雑種が生じる。, 「アザミの頭花（ノアザミ）」（写真注）、『週刊朝日百科植物の世界』2（アザミ ノジギク ハマギク）1-37頁。, 川窪伸光「日本でも発見されたアザミの「雌」」、『週刊朝日百科植物の世界』2（アザミ ノジギク ハマギク）1-39頁。, https://ja.wikipedia.org/w/index.php?title=アザミ属&oldid=72939416, 『週刊朝日百科植物の世界』2（アザミ ノシギク ハマギク）、朝日新聞社、1994年4月24日発行。, 佐竹義輔・大井次三郎・北村四郎他編『日本の野生植物 草本III 合弁花類』、1981年、平凡社.

Cirsium vulgare est une plante commune qui pousse en terrain découvert (chemins, clairières, décombres, terrains vagues...). It also was a top producer of nectar sugar in another study in Britain, ranked third with a production per floral unit of (2323 ± 418 μg). The leaves are stoutly spined, grey-green, deeply lobed; the basal leaves up to 15–25 cm long, with smaller leaves on the upper part of the flower stem; the leaf lobes are spear-shaped (from which the English name derives). The tap roots can be eaten raw or cooked, but are only palatable on young thistles that have not yet flowered. The stems can be peeled and then steamed or boiled. Cirsium lanceolatum bull thistle This plant and the related entities and synonyms italicized and indented above can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in different places, and some are listed above. Some farmers, due to its usefulness as part of the natural food chain, may find it useful to allow it to grow in beetle banks. [13], Spear thistle is designated an "injurious weed" under the UK Weeds Act 1959,[18] and a noxious weed in Australia[17][19][20] and in nine US states. Cirsium vulgare (Savi) Ten. Despite this label, the plant has beneficial qualities beyond its very high nectar production. The spiny, spreading, winged stems are up to 7 ft. (2.1 m) tall. Stem: generally 1, +- openly branched in distal 1/2, loosely tomentose, often glandular-hairy. [11], It is a tall biennial or short-lived monocarpic thistle, forming a rosette of leaves and a taproot up to 70 cm long in the first year, and a flowering stem 1–1.5 m tall in the second (rarely third or fourth) year. The supports for pollinators and pest-eating birds could outweigh its drawbacks. The plant provides a great deal of nectar for pollinators. It is also naturalised in North America, Africa, and Australia and is an invasive weed in some areas. Cirsium vulgare, the spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus Cirsium, native throughout most of Europe (north to 66°N, locally 68°N), Western Asia (east to the Yenisei Valley), and northwestern Africa (Atlas Mountains). アメリカオニアザミ（学名: Cirsium vulgare）はキク科アザミ属の多年草。日本には本来分布していない外来種。和名に「アメリカ」とあるがヨーロッパ原産のアザミであり、誤解をさけるためセイヨウオニアザミと呼ばれることがある。 It produces seeds eaten by the American goldfinch, down from seed pods that is used by those birds for nesting material, and serves as a host plant for the Painted lady butterfly. アメリカオニアザミ（学名: Cirsium vulgare）はキク科アザミ属の多年草。日本には本来分布していない外来種。和名に「アメリカ」とあるがヨーロッパ原産のアザミであり、誤解をさけるためセイヨウオニアザミと呼ばれることがある。, 日本には、北海道、本州、四国に移入分布する。北アメリカ、アフリカ南部、オーストラリアでも外来種として定着している。, 茎の高さは0.5-1.5m。大きいものは2mにもなる[6]。7-10月頃に紅紫色の頭状花を咲かせる。根生葉は羽状に深裂しロゼット状になる。葉や茎、総苞片には鋭い棘があり、手袋をしていても貫通するため注意を要する。一年草もしくは二年草。種子はタンポポのように綿毛で風に乗って拡散する。, 日本へは北アメリカから輸入された穀物や牧草に混入して持ち込まれた[7]。1960年代に北海道で初めて確認され、本州や四国でも定着しているが、特に北海道に多い[8]。, 利尻島や世界遺産の知床国立公園などの自然度の高い地域に侵入し、在来種と競争し駆逐している[8]。ニホンジカはアメリカオニアザミを食べないため、シカの多い地域（知床など）では本種が増えている[9]。また、牛などの家畜も本種を食べることはなく、酪農地帯では放牧地の害草として知られている[10]。, 外来生物法により、要注意外来生物に指定されている。棘を有するため、抜き取って駆除するのは大変である。, 大阪市立自然史博物館第50回特別展「知るからはじめる外来生物 〜未来へつなぐ地域の自然〜」, https://ja.wikipedia.org/w/index.php?title=アメリカオニアザミ&oldid=78860168.
