Now on 5 years of growth originally from a cutting, I believe this is another one of those stories where some HT's especially do better when grown on their own roots. I've seen so much solid evidence on (not only) robustness, but also the ability to have such perfectly formed and nicely opening buds. There's no comparison.
This one seemed to start out slow the first year, then the second year showed a little promise, but by the third year, FC was a nice strong grower. It seemingly appreciates a hillside, where the roots have a good chance to experience water, but never setting on the roots. Secondly, it also does amazingly with all morning sun and shade by 2pm. Many years back, I had this one as a bud graft, and it seemed to lack the depth of the color hues, and I certainly don't recall the irridescence in the petals as I see now (the photos I supplied display this well). It reminds one of the irridescence of Dolly Parton HT.
If there was one drawback with this particular specimen, it would be the lack of longer stems. Though it tends to have a very oversized (5 1/2" flower), they never flop, even in rain, simply because the stems are firm and stout.
Lastly, the fragrance character on this is superb. A deep clove with a hint of damask and marzapan. It's always a favorite in the vase.

Considering the testimony of Chill Out! Roses in the thread about Typhoo Tea, perhaps the hardiness rating for FC could be revised? I have also known FC to grow back after a zone 5 winter. It is not cane hardy, but the roots do seem to survive. My plant is grafted, but it was FC itself which returned in spring, and not the infamous doctor.
