The "Velvet-leafed Rose" is a survivor - the plant I photographed today is on a road verge, and was hit hard by glyphos a couple of years ago. In conditions of plenty of water (eg Ruston's in the days of flood-irrigation) it is a rampant grower. It can be unattractive, with faded old blooms among the new, and it has an irritating habit of producing bunches of flowers on the end of leafless stems when you want to show it off at the Spring Rose Show. ("Why do you say it's velvet-leafed, when it hasn't got leaves?")
The best use I've seen of it was at the Pinjarra Heritage Rose Garden in Western Australia, growing through Fantin-Latour - similar blooms but vastly different in size. Charming.

Does anyone know what the "Unknown Warrior" rose may be?
I am wondering if it could be the rose I wrote about in the Heritage Roses in Australia journal in 2005, [Vol 27, no. 3, p16]. At the time I called it the "Velvet Leafed Rose". It looks like 'Laure Davoust' but with smaller velvety leaves and smaller, one-inch lilac pink flowers, one by one fading to white, and a green pointel. I also considered R. beauvaisii, courtesy of Ivan Louette's website, but came to no conclusions. The "Talbot Rose" in Bermuda sounds the same rose.
