Spear Thistle and Common Ragwort are native plants that provide valuable resources for wildlife.
Yes they can cause problems in specific contexts. Thistles can become tough weeds in crop fields and ragwort can be toxic to farmed animals, especially if it is dried and eaten in hay (though I’ve seen plenty of examples of it growing in pastures where the grazing animals just avoid it).
As far as I can see, it is not illegal to have either plant in your garden, despite what the article says.
If you do have them they’re certainly providing benefits for wildlife. The only issue that might arise is if you live next to agricultural land that is having problems with these plants and your garden stock is continually spreading back into the fields.
This is not a problem for the majority of people, and it doesn’t mean these plants are inherently dangerous or bad. The unfortunate consequence of these kind of articles are that people start ripping out these plants wherever they find them.
Near me, people pulled up ragwort growing harmlessly on a public verge because they thought they were doing a public good. Those plants had been providing food for caterpillars, butterflies, bees, and other insects. Removing them just meant there was less food for wildlife, and less beauty and colour around.
These are native plants that wildlife depends on. A better article would have this nuance and would share details about the real benefits provided by them in the right contexts.
