I can understand the ivy. There other I have heard of but some I don't recognize. But I don't understand why butterfly bush is considered invasive ? I have one a I planted probably 6 or 7 years ago and it hasn't spread from where I planted it. I've planted a few more because the bees and butterflies love it.
Is it the same as this

I know you said different plants can have the same names so maybe its different from what we call butterfly bushes?
Mumsy how did you make out with the bees? Are they all gone since you sprayed them?
The hive under my barn porch were a small ground dwelling hornet. They are now gone and haven't come back. We have left the Bald Face hornet nest we found in the Rhododrendron shrub alone until the first hard frost comes in October. I want to wait until they are hibernating before dealing with them.
All the plants on the noxious weed list I posted are non native. They are listed because in Washington State they crowd out and kill desirable native plants, are toxic to live stock or cause terrible skin irritation in people. I picked up a booklet at that booth that gives alternatives to the noxious plants.
I have a couple varieties of named Butterfly bush cultivars that are sterile. They have never set seed in my garden after twenty five years. If the State sees Tansy growing on private property here they have the right to come onto your property and remove it. They dig it up roots plant and all, bag it, and leave.
Many of the plants on the list get into hay fields and get baled up with the hay. Livestock becomes poisoned. Some noxious weeds that get in hay cause the animal to not assimilate vitamin B. Some of them can cause the milk produced to become toxic.
Others on the list clog the banks of streams, rivers, or lakes. Erosion can occur. Wild life habitat for spawning fish becomes compromised. The native flora cannot compete and riparian waterways are lost as beneficial habitat.
Plants I have enjoyed but now have started digging up and killing are Yellow Flag Iris. It has seeded all over my garden into massive clumps. My husband has to use a pick ax to chop away at the tangle of roots. One seed or small piece of root can grow a new clump. It was beautiful when in bloom but not worth it now. If it seeds into lakes or ponds, it kills by smothering out all other plants.
Another one I'm battling after planting is the holly. Every berry a bird eats and poops in my garden produces a plant. They are non native and you find them every where in the forest now. There are others.
