I have a few in my back yard I have been trying to eradicate for about
20 years. If you come up with something that works, tell me.
The best advice I have gotten so far is multiple doses of very weak
Glycosphate (Roundup) over several moths.

Not sure if they're classified out here, but I wouldn't be surprised if
they are. And yup - roundup will kill them, so long as they're small.
I tend to go the other way and mix it to double strength - seems to work
fairly quickly. I believe that you can over mix this stuff - too strong
and it won't work because it's relatively too thick.
I let this one grow because I wanted to photograph the flowers - well,
that's my excuse and I'm sticking to it :-) . A long-handled shovel
removed it with only a few spikes to me in revenge.
