A little detail, but you might want to correct the name from Irene to Irène, i.e. if you want to keep the name despite the fact you have stated on the same page: "The name 'Irene Watts' is incorrect for the rose described here, although that name is still used in commerce."
Does anyone know how well Pink Gruss an Aachen will perform in partial shade? The area I want to put one receives about 5 to 6 hours of sun scarttered throughout the day, but I can trim back some tree branches to allow more sunlight if necessary. Also, does anyone know how to pronounce the name?
Gruss an Aachen should do okay with 5 hours of sun, especially if it get the noon type of sun. Gruss an Aachen sounds like Gruss an, now you pretend to clear your throat to spit, Aaacken.
