Well I can't do anything with German. Nothing I've found has associated the plant in the thread title with butterworts (Pinguicula spp) or big sedums such as Sedum telephium (which we call orpine or livelong in the UK). I'll have to take your word that those awful hellebores might be the answer, but, to be honest, no plant I've mentioned here rouses poetic thoughts in me. But then again, as I know no German and think that the average person who speaks German for more than ten seconds is on the verge of projectile vomiting, I may not be the best person to ask...
When I saw the thread title I immediately thought of the plant we call sneezewort (Achillea ptarmica), but that's yet another weedy little thing that has its place but which doesn't immediately spring out as poetry material...
