I had read that the reason bocking is the "right" one is that because it's sterile it doesn't take over the entire plot. Is there any other reason, cos personally I can think of worse weeds to have...

(Comes back) - yes that is the only reason, from what I can make out. I figure as long as you don't let it set seed, and/or weed out any unwanted seedlings that do appear before they become established, it should be fine.
Just don't turn your back on it for too long!
One thing to try seems to be stratification. I think - someone please set me straight if I've got confused again lol - this means sowing it in autumn so that you are mimicking wild conditions of it being dropped one year, staying in the soil over the winter, then germinating in spring. I sowed some soapwort earlier this year which didn't come up and just as I was about to chuck it, I read somewhere that wild flowers, especially natives, sometimes refuse to germinate until they've been outside for a winter and that you shouldn't chuck away an ungerminated pot or tray until you've kept it for a year... anyway I've left the soapwort pot in a sheltered place and plan to ignore it for another 9 months or so at least...
Is that stratification?
