That would be Grace, klm. I just looked up Osiria and yikes!, it's highly susceptible to powdery mildew. But then so is Papa Meilland and I have a couple of those. If it gets it, my Papa Meillands just get a spray with a milk and water mix. That changes the pH on the leaves and that fixes it. Such roses are possibly best out in the open to get the sun and wind. Osiria is a beauty, it certainly has the Wow factor.
Sweet Antique is lovely. A bit like Bonica in colour and form, do you think, with bigger flowers? This is Bonica below of course.
