Mortimer Sackler might work. When grown as a climber, its longest canes can reach 10-12 feet, according to the David Austin website. The David Austin website says only that it's "hardy" without giving a zone number. Unfortunately the Help Me Find site lists only default information, so that doesn't help. One thing to consider is that the cement in the porch, as well as the nearness of the house itself in keeping that cement somewhat warmer during the night, might make for a slightly warmer winter microclimate in that spot too than in the rest of your yard. Mortimer Sackler does have some shade tolerance as well as being very low in thorns. It tends to grow rather narrowly upright, also sending out some long, fairly flexible canes that would be good to wind around your pillars. Plant the two roses near the porch and maybe 24-30" to the sides of the posts away from the center, and pull over the canes that want to grow long and help them go up the pillars, probably allowing whatever canes that want to stay shorter remain on the bush to look nice on a lower level. If you are concerned about how you'd paint the posts later, then put up a large-holed decorative metal chain in front of (or slightly to the outside edge of) each pillar. Use a large hook eye to hang it from at the top so you could unhook it and gently lean it out from the pillar to get the paint on the wood when you paint. Use the chain to anchor tie spots you can use to attach the rose to loosely, zigzagging it with as much horizontal action to the outer sides as possible. You might want to get a very long large hook eye to anchor this chain on the ground end too, to keep the rose reasonably steady, especially during periods of high winds. It might be possible to make this work more easily by using two chains for each rose instead of one, and that probably would work just as well in terms of appearance during the winter (or probably would look better). If you didn't like the way it looked or worked, then just take down the chains, and trim the rose's longest canes back slightly into a bush form. The limited amount of time I've had with Mortimer Sackler here in zone 7 doesn't make me an authority on this for your area... but it might be a decent guess that Mortimer Sackler would work out pretty well for you. I do like Mortimer and it stays healthy without needing to use chemical sprays. Assuming you decide that you like Mortimer Sackler after investigating it, you might consider buying four of them, not just two. Use the other two in front of the posts at the two ends, and you'll end up with blooming all along overhead and a sort of open hedging at the base across the entire front. Mortimer Sackler for sure does want to bloom, and for sure it will repeat bloom well in zone 7. If I ever buy another Mortimer Sackler, I'd buy it from Roses Unlimited, where it is available as an ownroot plant (within the "English Roses" group there). Ownroot is also a good idea considering your hardiness concerns; in the worst winter some year, you might have to cut out some dead wood all the way to the ground. With an ownroot, what comes back will still definitely be Mortimer Sackler. If you do go with the 4-Mortimer Sackler scheme, you might also consider planting a small line of low-growing hardy polyantha roses with contrasting color just in front of the Mortimer Sacklers. Some ideas: White Pet (Little White Pet), Baby Faurax, Marie Pavie, Margo Koster. Best wishes, Mary Here is a link that might be useful: Mortimer Sackler information (shrub use size given)

You want roses that throw out long, pliable canes from the base, and not too many. You don't want roses with rigid canes like Dortmund, or climbers that build on older growth like Jacob's Ladder, or roses that produce the right kind of canes but so many of them that you can't keep up with them like Chevy Chase or Louise Odier. One rose that works well on a pillar for me is the HP Ferdinand Pichard. I do need to go in and work on it two or three times a season, and occasionally tuck in a straying cane, but all in all that's not bad. Rosefolly

I'm totally confused about why my motives are questioned. Of course I care about the beauty of my garden...in all seasons. And the nature of the question/solution implies concern about the well-being of my roses. I guess some folks don't limit throwing manure solely into their gardens. I decided to buy the bamboo shades. Found some dark bamboo shades at HD and tried it out. I got 39x72" shades. Had to buy 2 because my pillars are rather large in height and circumference. I think there's enough space between the strips for aeration and it looks nice. I'll post a pic when I get it installed. Hopefully, we won't get too much snow before Christmas so I'll be able to cash in on all those greens headed for the compost pile.

I live in Florida, so we have different conditions, but I can tell what I have observed in my garden. This is Teasing Georgia's first year. Currently it is covered in blackspot, but I have not sprayed for a while. It is the kind of rose I think that gets a lot of blackspot, but does not defoliate. Florida is the blackspot capital of the world by the way. It had less blackspot in the hot humid summer than it now has in the cool dry fall. Other than the blackspot it is very healthy. Mine is grafted on fortuniana rootstock. It has not had a ton of blooms, but they are very pretty and have a light smell. The thing is a monster in my garden, it is at least as tall and my Don Juan climber. It puts out these stiff octopus canes.
