I understand what you are saying, but growing up the term 'weed' was always used in the 'undesirable plants' sense and the term 'invasive species' is more accurate when you are discussing them specifically. When I first started gardening, the guy who trained me defined weeds as 'any plant the client doesn't want growing on their property'.

Stuff like dandelions and such.

Dandelions are a complex topic. While some consider them "Noxious Weeds", other people recognize their value as important sources of food for insects, they attract pollinators, and they also release ethylene which is a gas that encourages fruit setting and fruit ripening, so they are sometimes grown as 'companion plants'.

Dandelions are only weeds if you don't want them there, like any other 'weed'.

This is the real problem. Where the fuck did you find a plant only native in South America?

It’s also, in the simplest way, incompetent.

All those weeds provide some ecological service in some way. If you look at my yard and note it's covered in tall straggly white flowers, you could say weedy, and be right. I would clarify that wild carrots are helping convert our heavy clay soil into good tilth, and supporting a massive number of pollinators and pest predators.

And why would we put up with yellow dock going to seed everywhere? It’s the most nutritious chicken fodder, and it also gives tilth to heavy clay.

Don’t get me started about dandelion!!

In favour of things which we have no use for as a status symbol.

kudzu, ivy, and any vine plants. although kudzu is now being combatted with the weevil.

F yeah, allergy brother/sister!
