More or less agree with rare exceptions.

I grow Japanese knotweed in pots to harvest does that answer the question? 😁

If we are harvesting/maintaining it there is a lower chance of escape to the wild but in lots of cases, no one cares, notices or is it really relevant. Here in the U.K we don't really have any wilderness left anyway. We had an ice age so all the 'native' plants are really just ones that were originally invasive plants from the continent when it ended.

Invasive theory usually is in fact 'non native invasive'. Here someone decided 500 years ago was the cut off for native so English ivy an invasive alien plant in the USA is fine in the UK because it's 'native'. Doesn't stop it being invasive, sometimes destroying trees etc but because its 'native' no one cares. There are many more fast growing invasive plants like ground elder, nettle etc all 'native'.

I do think a lot of the niches the invasive appear in is to help restore and environment a lot of the time. Its just we sometimes too stupid to see it. The Japanese knotweed is maligned as a disaster here ruining house and mortgages but its mostly media nonsense. I know we could be harvesting to treat our sick trees and plants instead of trying to kill it with herbicide, but the legality of it now as an invasive and the fear surrounding it makes it unnecessarily difficult to do.

I can appreciate it being a different story in somewhere very isolated like New Zealand though.
