I don't know most of the roses on your list and don't grow in a similar zone, so my response is limited. However, a couple of observations -
1. I don't know that William Baffin reliably repeats. You might want to find out from people who grow in your area, but I've heard it's a once-bloomer elsewhere. It's gorgeous and hardy - no fragrance that I recall.
2. Be careful that the pinks that you choose are not warm colors. I find that cool and warm tones clash. Zephirine Drouhin is a bit warm-toned, to my eye. (It doesn't repeat bloom much here, and gets disease - I've heard it's much better in other locales than California.)
3. You need some deep colors so that things aren't too bland. Purples, claret-red, deep pink, are all possibilities.
4. Can you grow Hybrid Musks? There are some wonderful ones that do repeat, don't get too big, are fragrant, etc.
5. No taller than your fence is, you don't need big climbers - more modestly arching roses or lanky long-caned ones like Gertrude Jekyll will do very nicely trained horizontally.

How fun! Be sure to post pictures!

If your fence is only 3' high you'll want to make certain any climbing roses you grow have very lax canes so that they can be easily trained along the fence. Climbing roses vary in the stiffness of their canes. Stiff-caned climbers will always try to grow uprightly for the first several feet of their length (even as high as 5') and so the more stiff-caned the climber the more it will resist being trained along a low fence and instead try to become too upright for the setting.

In your climate I suspect you'll probably want to consider Renae and Climbing Pinkie among your possible candidates. They're both too iffy for my climate (probably too cold for them), but I believe they're both popular pink climbers in the southern USA.

Another bushy rose with lax canes that sprawls a little that might work for you is known as Carefree Beauty. I have no personal experience with it, but I know it to be well regarded (although I don't remember whether any of the southern rose growers here endorses it).

Carol, I think I also have a little trepidation about how well climbers will do on a fence that is so low. Is there a possibility that you'd consider roses that aren't climbers? That would widen your choice of roses immensely since the vast majority of roses are in the 4- to 7-foot height range. You might be able to include some of the hardier tea roses, bourbons like Souvenir de la Malmaison and its sports, china roses, hybrid perpetuals, Austins of course and hybrid musks. No matter what you decide, I'm sure it will be beautiful.

As Ingrid says, with such a low fence you'll want lax-caned types of roses, like ramblers and some of the Hybrid Musks. Or you can grow roses as shrubs, not too tall ones, and not train them on the fence. 'Zephirine Drouhin' has something of a reputation for getting fungal disease in certain climates, and I think your area might be one of them. Be aware that it's a strong color. Ramblers are generally not repeat blooming, though. Hybrid Musks? Some are stiffer than others. How about 'Kathleen'? simple flowers of a kind of apple-blossom pink, beautiful foliage. I haven't grown it, but Helpmefind says it can be trained as a climber. 'Cornelia' is lax, but its color is strawberry, a little yellow in the pink. 'Moonlight' is also lax, with white flowers; ditto for 'Pax' with larger blooms. Then there are a lot of modern roses that others will have to tell you about. Some lower-growing shrub roses that come to mind as possibilities are 'Mme. Boll', commonly sold as 'Comte de Chambord', 'Jacques Cartier', 'Souvenir de la Malmaison' in the bush form, 'Gruss an Aachen' and 'Pink Gruss an Aachen', and 'Mlle. Cecile Bruenner', but you have to careful not to get its hefty though beautiful sport 'Spray Cecile Bruenner'. These shrub roses are all pink to pale pink with no yellow in them, fragrant and repeat flowering, and not too tall. I don't know how they'll be as to disease in your area.
The clematis are a fine idea. I think 'Jackmanii' is one of the greatest plants ever hybridized, and belongs in every garden where it can be grown.

P.S. Oops. I just went and checked out 'Gruss an Aachen' and its sport on Helpmefind and they say it has yellow tones in its pink. Still I'm leaving in the recommendation, but now you are warned.

I really appreciate all of your excellent suggestions. I understand now that the climbers may not be the best idea for my situation. As as Ingrid said, using different species will widen my choices. So back to the drawing board for me! Thanks again.

I also prefer cool colors in roses.
A few evergreen rosebushes will increase your bloom season by another 1 and 1/2 months to 2 months a year, these include
"Reve d'Or" a soft yellow with apricot that bleaches to palest peach in hot summer sun. We keep it grown as a 5 and 1/2' tall shrub but it also makes a beautiful climber. I would plant that in the very center of the beds as a taller shrub.
"Mlle. Cecille Brunner" is the full name of the shortest form of the rose of that name. This one grows to be c. 5 feet tall by 4 feet wide in our zone. Hortico.com sells it as do most vintage rose nurseries.
Tea roses have beautiful blooms that repeat more often than Hybrid Tea rosebushes grown under the same conditons: the smaller Tea rosebushes that can be grown in a 3'-6' plot include
"Lady Hillingdon", a soft hue of apricot, against plum hued new foliage. Easy to grow and a great favorite among Tea roses for more than 100 years.
"Mme. Antoine Mari" c. 5' X 4' heartbreakingly elegant light pink and cream blooms against pretty foliage.
"Westside Road Cream Tea": one of the smallest Tea rosebushes that matures at c. 4 and 1/2 feet tall, by c. 4 feet wide. vintagegardens.com and roguevalleyroses.com both sell this lovely rose. I have two of these flanking my front entry walk, beside two "Mlle. Cecille Brunner".
Noisette: "Nastarana" white and "Narrow Water" pale pink are both quite fragrant both maturing at c. 5 feet tall by 4 feet wide.
All Old Garden Tea rosebushes and Noisette rosebushes have abundant foliage and to my eyes, show a more graceful growth habit than the upright and rather rigid growing group of Hybrid Tea rosebushes, just my opinion.
A real advantage is that being evergreen, most Old Garden Teas and Noisette rosebushes keep their foliage through all but 4 weeks during winter, where I live.

Best wishes for a beautiful rose garden.

well, I am also growing roses in exactly the same way - a low line of climbers and ramblers supported by posts and wire, I have gone for some of the barbier ramblers because I have already grown a couple of these very low and the canes are nice and whippy. The multiflora ramblers also work well for me - Goldfinch, Ghislaine de Feligonde, Phyllis Bide and I have included a persian musk and a couple of spinossissimas as punctuation. Not only is this little hedge low, it is also narrow and pruning does have to be done throughout the summer but it is doable. I am not bothered by repeats so have been able to keep fairly close to the species (have included a couple of them too, such as the Ayreshire roses) As for clems, well you can do whatever you like with these - I tend to let mine sprawl around as ground cover. One word of warning though, my hedge is never going to look neat and tidy - it has bulges and lumps and odd canes which shoot off in weird directions. Still, all gardens are pure artifice and you are in control so have a go, specially since the forum members have made some excellent suggestions.

Cornelia is a lax-cane hybrid musk that repeat blooms. I can think of lots of ramblers that would work in your situation but do not repeat.

Again, thanks for all the advice. I have decided to go with shrubs, not climbers, along the split rail fence, one in each zig (or is it zag?) I will let the clematis vines climb on the fence. In keeping with my cool color design, I will plant multiples of the following David Austins. All have the rebloom,fragrance, etc. that I was looking for. And the colors, oh my!!
- William Shakespeare 2000
- Corvedale
- The Wedgwood Rose

Clematis will be multiples of Jackmanii and Prince Charles.
