Alas, I don't have the Alba yet, but have two of the pink species. My soil is about 7.0 and I mulch with pine needles, and these roses are lovely. I live at a 5200' altitude, Zone 4, western South Dakota. I give these own root roses no extra protection beyond what my hardy perennials get. There is some dieback over winter, more due to dry climate I think, but I've never lost either of these or the related Canadian bred shrub roses. The species rugosa are especially fragrant..

I bought this rose from a local nursery, and I know rugosas aren't supposed to do well in alkaline soil, or the LA climate, but it's been happily green and flowering for a couple of years now.
