I have to second this post. Buff Beauty has been a rather troubled plant for me. It started out well and sent out two big new canes in its second year, but since then has only produced new growth from on top the existing canes. These canes have grown heavy and are as flexible as rebar, but are very productive with flowers. I wish it would produce new growth from the base without my having to whack back the existing canes to induce it. That said, I love the flowers, especially in the cool spring and fall weather when the colors are a rich orange-apricot. Definitely one of my favorite roses.

I have to amend my comment from May of this year. I decided to lavish my Buff Beauty with more water and fertilizer this year and the results quite startled me. The first flush of bloom was as usual, starting around April 20 and carrying on for about five weeks. I dead-headed the flowers, fertilized and watered heavily and BOOM! The plant has thrown out new growth all over the place and sent out a several whopping new canes. Its second flush of blooms started to open this week and there are probably twice as many buds this time as in April/May. There are a couple of huge panicles of buds (probably 20 - 30) and scores of the regular clusters (of about 5 - 9 buds), and the flowers are bigger, too. I am really surprised and delighted. At this rate, the fall flush of bloom should be beyond spectacular.

I guess I've learned that BB likes a bit more water and food than some other roses. I have Radox Bouquet planted nearby and it has received the same treatment. RB has been very productive this year, but hardly the transformed rose BB is. All I can say is WOW!

New Dawn is an outstanding climber...no disease and good repeat. It is also quite shade tolerant. It's flexible canes are easy to train. If you want a better flower, there is a sport of New Dawn called Awakening. Mine took a year before they flowered, but they are worth the wait. Completely hardy in my garden. Be warned, however, that they get big very quickly.

One rose that blooms like mad all summer with only half a days sun is Abraham Darby. It can be grown as a small climber (8ft) and has a fragrance to die for. It does get blackspot, but it still never stops flowering. It has had very little dieback during the winter.

My favorite climbing rose has to be Westerland or its sport, Autumn Sunset. Both bloom very well, and have been completely disease free for me in Pennsylvania (blackspot heaven). Westerland also has a great fragrance (Autumn Sunset is not as fragrant to my nose). I have heard reports that they are shade tolerant, but I have never grown them under such conditions. In my zone 6 garden, they can lose a few canes during the winter, but come back very quickly. In colder zones, they might not grow well as climbers.

Other roses you may check out are Bubble Bath and Darlow's Enigma. They are climbers/shrubs and are supposed to be among the most shade tolerant of all roses and bloom non-stop. They are on my want list to purchase, but I have not personally grown them.

Hope this helps.
