on 7/15/2022 i (Asciencepotato) added a photo of a bull thistle as my first ever edit. i thought i added it to the gallery of images but it appeared on the side beside the references, and now the gallery of other images seems to have disappeared. i am worried i did something wrong and now they are gone. — Preceding unsigned comment added by Asciencepotato (talk • contribs) 18:44, 15 July 2022 (UTC)[reply]

On 9/3/11 an anon made significant addition to the "Thistle" article, which I undid as it was obviously only concerned with Scotch Thistle. However, this adjective is sometimes used for Cirsium vulgare and sometimes for Onopordum acanthium, and I wrongly copypasted the addition here. Mea maxima culpa - I should have noticed that several of the references expressly mentioned the name Onopordum acanthium. On 29/3/11 I was reverted by an anon [possibly the same from a different IP] in a way which resembled vandalism, so that was reversed by another user as well. However, I then noticed my botch-up, reversed myself and added the information (such as hadn't been there already) to Onopordum acanthium. My apologies to the anon(s) and Bidgee. --Thrissel (talk) 18:12, 2 April 2011 (UTC)[reply]

Cirsium vulgare is a species of thistle in the plant family Asteraceae. Native to Europe and Western Asia, it has become naturalised in North America, Africa and Australia, and is an invasive weed in some areas. It is a ruderal species, able to colonise bare ground, but also persists well on pasture as its thorny leaves and stems make it unpalatable to most grazing animals. The flowers are rich in nectar, attracting bees and butterflies, and the seeds are a favourite with goldfinches, linnets and greenfinches. The downy pappus, which assists in wind dispersal of the seeds, is used by birds as nest-lining material.

Section lacking citation

"Despite this label, the plant has beneficial qualities beyond its very high nectar production. 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. The monarch butterfly and other larger-sized butterflies can feed easily from the flowers due to their large size. 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. The supports for pollinators and pest-eating birds could outweigh its drawbacks. In areas where it does not form monocultures it may also be welcome as a part of a meadow landscape.[citation needed]"

This section lacks citation, and I believe it should be removed. Cirsium vulgare is a noxious weed in North America (https://www.fs.fed.us/database/feis/plants/forb/cirvul/all.html), and promoting positive ecological benefits of it with no supporting evidence is dangerous.
