It’s everywhere in the NW, it kills large trees, it is toxic for virtually everything to eat, is noxious to burn, and is an allergen to me. I have used it’s vines to make junk pole fence straps but even that they aren’t great for. I know there are several British isle ivies, but I call them all english so I can feel like William Wallace as I unleash my rage upon them.

It's the only weed I haven't been able to conquer on my farm. I've chopped it, dug it out, smothered it for a year, flamed it, and used several organic weedkillers.

Outside of ruining my garden soil, I can't easily control it. I have had to resort to digging down 8 inches to remove the stolon of every shoot I see coming up. That's quite an impossible task when you're growing on 4 acres of old pasture area. It may possibly take the rest of my life to clear my growing beds.

Rhizomes is why and lack of available biological control.
Cirsium arvense is similar but I have hope for a new biocontrol initiative I heard about.

Mulch with cardboard (not the best, but solid enough) covered with 10+cm of normal mulch seems to keep it from sprouting. I’ve heard rumors of lawn rollers covered with yoga mats, but haven’t tried that yet.

Tribulus Terrestris is a plant used for its many health benefits. It can protect the heart, help treat depression, and even increase libido. What's not to like?

Invasive, not good for anything. Extremely fast growing, hard to stay ahead of in removal. Seed dispersal is by the millions, white sap at the slightest touch. No biological control, worthy of Agent Orange bombing by a B52!
Whoever brought this weed to Australia I hope their souls burn in purgatory for eternity!
Suffice to say, I hate everything about this useless plant.
The plant can be used as an alternative food source for caterpillars of the monarch butterfly. Although monarch caterpillars are not known to occur naturally on the plant, they will readily feed on leaves when supplies of Asclepias physocarpa have run out.

2) Spreads incredibly fast to my garden beds by creeping, almost impossible to remove the roots competely & backbreaking to try to do so, spreads from tiniest bits of roots left
3) Covering the bed for one year is the only remedy that really works. And I mean covering it so that you exclude ALL light. A tiny hole in your cover means it finds its way to that spot and lives on.
There are uses for this plant. Animals like eating it and the root has some medicinal purposes. So, it's not all bad.
Still, as it causes me so much work and forces me to use black plastic mulch, I don't like it.
I hesitated about whether I should say creeping thistle (Cirsium arvense), or horsetail (Equisetum sp.). Those are also pretty impossible to weed and I have to use plastic if I want to get rid of them. But, thistle with its deep roots at least helps to fight soil compaction and horsetail spreads slowly compared to quack grass. So yes, bloody quack grass is the winner on our farm, in my opinion.
