I love white roses best I've grown several fragrant white climbers that can take heat but none that are truly thornless. I left my M.A.C. when I moved because I didn't like how pink it was, I prefer white roses that always bloom white. The following roses are not smooth stemmed, but have fewer prickles than average for their class and all are white and fragrant and grow well here in Northern California where summer temps are more often in the 80's than 90's: To my nose both these two rate an FFFF for maximum fragrance. 1. 'Snowbird' 1936 Hatton, also has a climbing form. "Snowbird" is the most fragrant vintage white H.T. that I've ever met. It has large flowers that bloom in an lovely antique floral shape, that remind me of 'Sombreuil'. "Secret Garden Climbing Musk' has small blossoms that have an intense spicy scent which Jeri Jennings describes as smelling like gingerbread. Mine is c. 5 feet tall now and has very few prickles, though more might come. To my nose "Snowbird" is far more deeply fragrant, and Secret Garden Climbing Musk" is quite a bit more intensely scented compared to "Mme. Alfred Carriere". Another of the most fragrant white roses I've ever grown is 'Nastarana". I grow the bush form which has a few but small prickles and I've read that someone who posts here grows a climbing form of this rose on the east coast. One of the Canadian nurseries might still sell it. I also grow cl. "Mrs. Herbert Stevens" Scent is a refined blend of sweet lemon and mixed floral. Less prickly than the average H.T. but not thornless. Can be grown self- supporting as a large Tea sized rosebush c. 8 feet in all directions. Twiggy growth habit inherited from the Tea class which also gave it its very early bloom habit, the only H.T. in a garden here, that blooms as early as the Tea roses do. Good luck in choosing a rose that you will love, Luxrosa

I must have lost my mind because I just ordered Crepuscule, Reve D'or, AND Climbing Crimson Glory, due for delivery in September. I have been evaluating my property and decided that I could find the space for few climbers, two of those listed above will hopefully find happiness growing up the side of my house, I am hoping to get an "invisible trellis" installed in one or maybe two places on the outside of my house for them. The remaining rose(s) will grow against an ugly chain link fence that divides mine and my neighbor's back yards. The one that goes in the back yard will probably have the most growing space, but will also have to deal with the most shade, I am thinking maybe crepuscule could go there? Out of these 3 which one do you all think will grow the largest/smallest? I know ramblers get quite large and can really devour any structure in their path, but since crepescule isn't technically a rambler, I didn't know if it would have the same massive size, or if just the shape of the plant is similar to a rambler. I have read in various places that all three of these roses can get quite large. I visit HMF often, but I still seem to have a hard time deciphering growing habits and sizes, it seems like they can vary widely based on climate and just the individual gardener because I am constantly reading conflicting statements of size of one plant as different based on what website I'm looking at. I am a little intimidated by the task I have put ahead of myself, I've never had a climber, ever, but if I never try it will never happen, so here goes nothing!

So many helpful & descriptive responses! From what almost everyone says about Crepuscule, it seems to be the perfect rose, fragrant, constant bloomer, almost thornless, disease resistant.. what more can you ask for?! I decided that this one would be my first climbing purchase ever, and I found a website through "Dave's Garden" for a nursery called Niche Gardens, which had it in stock in 1 gallon containers. I am excited to see how it does, however now I have all these other amazing suggestions to consider as my second and third climbing roses. I think I will put in an order at RU for the cl. Lady Hillingdon for next year because I just cannot get over the beauty in all the photos I have seen & I must give that rose a try. Reve D'Or looks very intriguing as well, it seems to have as good of a repeat as Crepuscle, with a softer yellow/apricot coloring that looks almost ivory.. very lovely. Buff Beauty looks lovely as well but I am not sure that I will have room for another rose that gets huge, I am sure Crepuscle will give me a run for my money in the garden space department in a few years. Kingcobb, I know that Don Juan is a red, but since everyone seems to comment that he is so fragrant & such a heavy bloomer I think I may have to add it to my ever increasing "find a place for this rose" list. I think it would add some nice contrast to all this yellow/apricot. I actually already have a rose that I have decided must be Teasing Georgia, I bought it cheap as an unlabeled, abused little thing from the "alley of impending doom" at my local nursery, and I have been nursing it back to health for a few weeks now. I posted photos of it here and a few helpful members have convinced me it is probably a Teasing Georgia. So if I can get it looking good and strong again, there is another climber for me to play around with! I'll link that post at the bottom. Has anyone had any experience growing Pat Austin as a climber? I saw an image of it on this site somewhere and it was jaw-dropping, it finally made her "weak necks" seem like a good thing, because she looks beautiful from below. Thanks again all! Jessica.

Obviously the popular and safe bet is New Dawn, however bloom varies for some as far as repeat. It is definitely most vigorous though and easily gets to 20ft once it matures. Mine is in it's 1st year and it is every bit of 9ft right now and still going. New Dawn is mostly a white, with a pink tinge to it. From a distance it tends to look mostly white though or faintly pink. Many people claim New Dawn doesn't have much of a fragrance, but mine definitely has one, especially when there are many blooms on at one time. It's certainly not strong, but what the blooms lack in strength, they make up for in numbers. Where exactly are you training it on your porch? Are you putting up white lattice, along the fence, etc? I am SURE there are people with many more suggestions and even better ones from their own experiences. Here is a link that might be useful: HMF New Dawn
