Anybody grow Chamaenerion Angustifolium Album?

Does anybody grow this? I am aware it is related to the dreaded Rosebay which I already "grow" despite my best efforts to get rid of it. With this in mind I was wondering if it too sets seed with gay abandon and once you have it it's nigh on impossible to get rid of it.
Having a very big garden with big herbaceous borders anything which is fairly fast at increasing is good for me but there is a limit! I also like white flowers and if it's like it's "brother" the white form won't need staking or support, another huge plus as far as I am concerned.

 

Hi silu, I used to grow the white Rosebay Willowherb and it was very well-behaved compared to the pink. Don't recognise this name at all, though. All I could suggest is to grow it somewhere with easy acces for a hoe, just in case

 

Thanks noisette. It gets good reviews but always better to hear from people who don't have an axe to grind so to speak! Agree awfully posh name for white Willowherb
