Good luck with Chloris. It's an alba I'd forgotten about. Looks great.
When I gardened in NJ, some of my favorite roses were Albas. I was especially fond of Konigen von Danemark (Queen of Denmark). I think the nursery where I bought it has since closed, but I expect Pickering might have it. And maybe High Country Roses.
If memory serves me correctly, David Austin's Queen of Sweden resembles Chloris, a bit. Not sure if it will be quite so well branched as an alba; but I do know DA admires albas greatly and has used them in his breeding program.
