It's funny isn't it. I like the plant but have a well bahevd clump of the pink stuff that isn't invasive at all. I would dearly love to have some of the white but it just won't grow. I have deeply fertile akaline loam which varies from well drained to boggy and the stuf fthat grows for me isin a shady, dampish bed that only gets full sun from 3pm between the equinoxes.
Good luck with getting rid. I can sympathise having my own problems with the usual suspects - creeping buttercup, nettles, thistles, couch grass and mare's tail which all love my soil and grow with gay abandon no matter how much I weed them out or paint with glyphosate.
I'm the same as you Obs. My pink September Charm is well behaved. I've only split it once in several yrs, purely because the clump was thin in the middle. I have small spring bulbs growing on top of the clump as it's always late in restarting, so a doyble use of the space.
I would love to grow the white Honerine Jobert, but it just doesnt like 'me'. 3x I've tried, no luck. So now I just remember the little front garden full of it just by the entrance to St Catherine's college, Oxford. J.
