Thanks, they really increase fast, I'm going to have to thin most of them this fall. My Conca D'or hasn't bloomed yet, and they are shorter this year, but they increased from 2 to 4 stems and one from 1 to 3 stems, so I guess they will be taller next year.
I used to have this pink one called Robina, It had one single stem for about 4 years, and then it increased to two. That winter we had the cold temps down to minus 22 degrees, and I lost it. I really loved this one, and it was so very fragrant. I haven't found a source for it, I'd sure like to replace it. I had gotten it from a booth at the Chicago Garden expo.
I can tell by the dead grass that this picture was taken during the summer of 2012 when we had the long spell of temps near 100 and no rain.
