I've seen that Theresa Bugnet and it's really really nice.
Rose Marie Viaud looks very similar to Excellenz Von Schubert (to me, anyway...) .
It's such a challenge to find a rose that will "work" where you want it, isn't it ?
I'm experimenting with growing climbers on arbors combined with other blooming vine-like plants. That way, if the rose isn't a constant bloomer, the other plant usually has some flowers on it and when they both bloom at the same time it's very cool. Common old ivy geraniums work well for me when combined with smaller climbers. Just weave them up through the arbor instead of letting them sprawl on the ground.
Below is a plain old orange ivy geranium combined with cl. white iceberg. The rose is dwindling down for the season, but a month ago the two looked good together. This is a shady spot most of the year and Iceberg seems to tolerate less than full sunlight.
