Hi slada,
In the Roses Gallery, check out the thread titled "Roses A" near the top. Seil has posted her beautiful photo of Appleblossom Carpet rose. There is also a lovely Apricot Drift rose photo posted by sara-ann, I believe. It's another gorgeous landscape rose. Diane

The original bright pink carpet rose is the tallest and most vigorous in my garden. Mine got huge in a very few years, probably 8X8, was packed with blooms all summer until it got hit by RRD. I've had Apple Blossom Pink, white, and dark red carpet roses, but none were as strong as the original pink.

I have 2 Apricot Drifts and 2 Coral Drifts. I love them, but they don't get tall enough to be seen over your wall (at least not here in my climate). Someone posted a couple of months ago about their Peach Drift getting way taller than expected...I want to say 5 ft. Not sure if that was a fluke or if Peach Drift is taller than the other Drifts. I had 3 Lady Elsie May roses in another garden when they first came out. Those were great landscape roses and would fit your height requirement. I would definitely recommend them as continually blooming, low maintenance shrub roses with very good disease resistance in my climate. Currently, I have 2 OSO Easy Paprika roses that would also work behind your wall. They bloom all the time and are at least as disease resistant as Knockouts for me. Sorry, but no experience with the Carpet Rose series other than the original pink when it first came out, and I really can't remember how big they got or how well they performed.

I have to say that my Appleblossom Flower Carpet is pretty much bullet proof. RARELY even gets any kind of diseases and blooms all summer long. It's pretty much self cleaning too as I hardly ever have to dead head it. Mine spreads out in a nice circle about 4 feet wide with an occasional cane that goes up to about 3 feet in height. But if you want to train it to go up that wall it's pretty flexible and should be easy to do.
