I've never gardened in the South, so I have no personal experience with this rose, but if you're open to considering older roses, Climbing Maman Cochet is about 100 years old, but I believe it's still popular in the South (at least among knowledgeable Southern rose enthusiasts), where it grows best. It isn't a modern rose. It's one of the "Tea roses", which were the direct ancestors of today's "Hybrid Teas". Most of the Teas prefer the heat to the cold. They were bred from wild roses native to the Asian sub-tropics (that grew wild in southern China, northern Indochina, and northern India), so they're well adapted to hot humid summers. A 20' trellis is a tall trellis, but I believe this rose is capable of filling such a trellis. By the way, if your idea of "pink" includes the peaches, apricots, & salmons then there are several other Climbing Tea roses for you to consider, too. Oh, and one final thought. As a group the tea roses tend to have flower stems with "weak necks" that are incapable of holding the fully open flower upright. That can be a frustrating fault in a blooming rose bush, but on a 20' climber that's actually an advantage, if you're mostly looking up at the trellis from the ground. If that's the way you'll be looking at the trellis most, then a climbing rose with weak-necked flowers is a climbing rose whose open flowers nod down at you as you look up at them!

Going along with micahelg's statement, I am growing "America." It is a large flowered climber with high-centered blooms that resemble a hybrid tea. Unfortunately it is not cane hardy. It is too close to a shade tree, and only grows 5'. I wish I could see grow here in a sunny location. The flowers are coral colored and beautiful. I also grow Spectra, another large flowered climber, that I absolutely love. It too has high-centered hybrid tea style blooms. In France I believe it is regarded as a hybrid tea. Mine will reach seven feet tall. However, it is not a Zone 5-A rose bush. I have it in a very protected location that gets full sun but it protected from the wind. Although it gets cold temps, it would mimic a Zone 7 micro climate. The roses in this bed are tremendously vigorous. I also am growing what I believe is Dr. Huey (the common rootstock used for roses) and it puts on a tremendous display. It is a great climber and once was sold in commerce. It is cane hardy.

Lala - the pink rose you circled in the pic is 'Climbing American Beauty' (which is a seedling, NOT a sport of 'American Beauty', and not related to 'Miss American Beauty'. Cl American Beauty (1909) is once blooming, but it blooms very prolifically for a month or so, and then there is scattered bloom for more months on new growth. HMF says it is hardy to zone 5, as it is a Wichurana hybrid. Vaporvac - in Elaine's first pic, the purple rose is Kim Rupert's 'Lauren', and the peach colored rose is Peach Drift (this one is a tree rose which Lauren is eating!). In her second pic, the rose is Korde's 'Summer Wine' (NOT the same rose as 'Summerwine'). Jackie

I will try to wrangle the canes down. Is a fun adventure for sure. Florentina is definitely getting larger and stronger each year so far. I was happy to have so little die back too. I probably will have to move other roses which are planted quite close together. Here is John Cabot today. It has smaller canes coming up from the base as well as long laterals poking out from the sides. I gave it what I thought was a considerable pruning this spring. It is on the east side of the house so maybe does not get as much sun as it would like. The clematis usually blooms after the rose, so this is a different experience too. Also deer nibbled on it some before I put up the fence. For a while I had a folding table protecting it so the base was quite shaded. Maybe there is too much going on around the rose with the clematis and geranium. It does still have buds to open yet though and overall to me it is a beautiful rose. But I am not sure if I should be doing something with the longer laterals. Thanks for all your input!
