I learned this at school as "Soft red rose, red rose of May" I will try to pull it out of the depths of my memory and come back if I have any luck.

I can confirm Snuffy's guess though, the tunes are the same, and the words do translate across (allowing a little license to the translator to make it scan/rhyme). I suppose it could be a translation English>German, but it feels like the other way round.
