Sadly, Cirsium discolor has been targeted for eradication largely due to the invasive behavior of its non-native cousins, the European Bull Thistle ( Cirsium vulgare ) and Canada Thistle ( Cirsium arvense ) which, despite the name, is not native to North America. (floydnativeplants.org)

One of the worst invasive pests here is Cirsium vulgare or Bull Thistle. (nargs.org)
Asteraceae3
Cirsium arvense is a perennial species of flowering plant in the family Asteraceae, native throughout Europe and western Asia, northern Africa and widely introduced elsewhere. (wikipedia.org)
Cirsium arvense is placed in the subtribe Carduinae, tribe Cardueae of the family Asteraceae. (wikipedia.org)
C. arvense is a noxious weed of the Asteraceae family. (cgiar.org)
This mechanism has only been observed in pistillate plants for dioecious C. arvense. (wikipedia.org)
Four species of alien plants were listed for the first time for the flora of Ukraine: Arabis procurrens, Lactuca sibirica, Polanisia dodecandra subsp. (sagepub.com)

Among field weeds Apera spica-venti, Cirsium arvense, Fallopia convolvulus, Raphanus raphanistrum etc. can often be found. (berezinsky.by)
Worst invasive2
Given its adaptive nature, Cirsium arvense is one of the worst invasive weeds worldwide. (wikipedia.org)
Among the worst invasive species that are present at Hidden Springs wetlands are purple loosestrife ( Lythrum salicaria ), mis-named Canada thistle ( Cirsium arvense ), and reed canarygrass ( Phalaris arundinacea ). (boisefrontnature.com)
Invasive2
C. arvense is a serious invasive species in regions where it has been introduced. (cgiar.org)

Weeds1
Cirsium arvense is one of the most economically important agricultural weeds in the world. (asu.edu)
Perennial1
C. arvense is a tall, herbaceous, perennial plant, forming extensive clonal colonies from an underground root system that sends up numerous erect stems each spring, reaching 1-1.2 m tall (occasionally more). (cgiar.org)
Native7
Native (281) and alien (243) taxa of the flora were analyzed. (sagepub.com)
Only three genera in Cynareae are represented by native species in the New World, and of these Cirsium is by far the most widely distributed and diverse. (swbiodiversity.org)
Native species of Cirsium range from sea level to alpine and from boreal regions of Canada to the tropics of Central America. (swbiodiversity.org)
Cirsium discolor (Field Thistle) , together with Cirsium muticum (Swamp Thistle), is Floyd County's native thistle, and a staple of any butterfly garden. (floydnativeplants.org)
Cirsium discolor can be distinguished from non-native thistles by the white woolly undersides of the leaves which none of the non-native thistles have and all North America's native thistles do have. (floydnativeplants.org)
Cirsium discolor is noted of Special Value to Native Bees by the Xerces Society ( Wildflower.org ), as a keystone species for 15 species of native bees by Dr. Doug Tallamy, and as a provider of nesting habitat for some native bees including leaf miner bees which nest in the hollow stems ( Xerces , 2017). (floydnativeplants.org)
Canada1
Large patches of purple-flowered Canada thistle ( Cirsium arvense ) grow at the edge of the marsh, interspersed with tall stalks of poison-hemlock ( Conium maculatum ) covered with small white flowers. (boisefrontnature.com)
Checklist1
Olga V. Melezhyk: https://orcid.org/0000-0003-3882-7102 ______________________________________________________________________________________________________________________________________________ A B S T R A C T For the first time we compiled a full checklist of the spontaneous flora of O.V. Fomin Botanical Garden of Taras Shevchenko National University, Kyiv. (sagepub.com)
In addition, there is a list of introductions which have high naturalization rates and over time could replenish the composition of the spontaneous flora. (sagepub.com)
Ten families which total 55,0 % of the specific and 51,2 % of the generic flora composition are the most abundant in species. (berezinsky.by)
Primary tillage systems had a more significant effect on the composition of the weed flora, weed density and diversity, and weed biomass than did crop rotation patterns. (ifvcns.rs)
Grown1
Cirsium discolor can be grown in most any sunny mesic cultivated garden, though it is a widely adapted pioneer species able to scrape out a living in many disturbed or subxeric habitats. (floydnativeplants.org)
