Here near Buenos Aires, which is a lot warmer than Germany, 'Rolf Fiedler' evidently resent chilly weather and this is very important. In the wild both 'Rolf Fiedler' and pure uniflorum grow at the same altitude and it is incredible that one population is very hardy and the other dislike cold so much. This for those that say they are the same species. Besides that, there are no records of intermediates, anywhere in the world, although many grow them in close proximity. Forms of uniflorum intercross like rabbits and there are many intermediates in any garden, often of an inferior type.

Actually, the late Traub published the changes at least 40 years ago.

This was just mentioned. Tristagam peregrinans location was TYPICALLY described like if you say "California, Sierra Nevada". You would expect to read next "now go find it!!!"  Central Uruguay. 'Rolf Fiedler' is from E. Uruguay, and more to the south than the former.
