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)

Pasture thistle1
Hill's Thistle often goes by Latin name Cirsium hillii but it is now treated as a variety of Cirsium pumilum (Pasture Thistle), var. (minnesotawildflowers.info)
Smooth Blue Aster1
Like the hairs on a dandelion, the Smooth Blue Aster pappi (ring of fine feathery hairs surrounding seeds) allows the seeds to be spread by the wind. (birdwatchinghq.com)
Bloom4
With more than 70 species in bloom, Water Canyon (as usual) is the place to visit. (inaturalist.org)
On a single day in mid-June, visitors to the meadow identified thirty-four species of wildflowers in bloom, all of which are visited by pollinators--among them, great spangled fritillaries. (sharpeatmanguides.com)
Non-native thistles generally bloom in spring and have more spines. (ncsu.edu)
Asters bloom well into November, and are often the last flowers seen along the trails on a late fall hike. (montara.com)
Swamp Thistle1
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)
Spines1
Thistle heads are surrounded by spines and sport bright pink to purple flowers. (blogspot.com)
Spiny1
There are so many species from such a lot of genera that I thought I'd start a board that was more general - Panayoti and others have been rapping on spiny plants on the Cactus discussions and I love pricklies (although Monica doesn't so I have to keep them out of touch with one another) but above all I think thistles of all sorts are the great gems. (nargs.org)
Family1
According to Montana Plantlife.org , it's belongs to the Aster family. (blogspot.com)

Native thistles attract many butterflies (including the monarch butterfly) with their copious nectar. (floydnativeplants.org)
A fritillary patrolling the meadow stops to sip nectar from a thistle. (sharpeatmanguides.com)
This will encourage species such as clover, daises and especially dandelions which give the first source of nectar after the lean colder months. (linnelsfarm.com)
It's safer to have a good selection of original wilder species or simpler forms of flowers where the pollen and nectar can be foraged with ease. (linnelsfarm.com)
Avoid those garden centres selling Sedum 'Autumn Joy' or 'Herbsfreude' which is a nectar-free hybrid - you definitely need the spectabile species, and preferably several of them. (sussex-butterflies.org.uk)
Clover3
The queen favors apple and plum blossom while the workers appreciate red clover, Penstemon, Asclepias (milkweed), Cirsium (thistle), Eupatorium and Spiraea (meadowsweet). (wikipedia.org)
The usual species are along the Upper Crossing Trail, notably White and Purple Prairie-clover, Scurf Pea, and James' Buckwheat. (inaturalist.org)
In 2018 the state had produced over 100,000 pounds of honey from a variety of flowers such as clover, aster, buttonbush, and more. (beeswiki.com)

Discolor6
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)
As a result, if you decide you don't want to continue growing Cirsium discolor , cut the flowers before they go to seed or remove the seedheads before they are dispersed. (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)
Prickly1
The combination of that plus the densely hairy, but not prickly, stem and leaf shape differentiates it from other thistles when flowers aren't present. (minnesotawildflowers.info)
Buckwheat1
Adults use composites, asters, nude buckwheat. (cnpsslo.org)

It's a good idea to plant large drifts of single species to save the bee's energy. (linnelsfarm.com)
However, I did find and photograph a Hill's Thistle plant and you are correct that when you come upon them, they are a spectacular sight! (minnesotawildflowers.info)
Most leaves of California Thistle are found at the base of the plant. (smmtc.org)
Tall3
The Texas thistle grows 2-6 feet tall, without branches, or sparingly branched near the top. (wildflower.org)
