Can set OP hips. Average 1 or 2 seeds per OP hip for me though.
Edit: excellent germination (75%) from those seeds!

Recently bought, as a vigorous 1 y/o plant, with many branches and full of flowers.
I had read about it before and was not about buying it... but I saw (and smelled) it at a local plant dealer (downtown Genoa, Italy), and changed idea immediately.
It's definitely not a white rose, more of a faint cream with pink hints, but it's beautiful nonetheless. Flowers are a smallish perfect cup, they're not very long lived, but they're freely produced, generously, in groups. And its fragrance... for me it's really gorgeous AND powerful, lemon, alba rose (Felicite Parmentier) and a little bit of myrrh, all this beautifully mixed. While it's true that it doesn't carry far, I found it really powerful.
I have it from just one week (and wind broke in half one branch two days ago), but until now it's really gorgeous.

One of my favourite roses, one of the few that manage to have the beauty and grace that Austins always have and blooming ability and health to match modern standards. It's compact and has rather smooth stems, and the plant as a whole just looks good.

Its fragrance is one of my favourites, too. Not too strong, but extremely complex and interesting. Botanical notes, juniper, lemon zest, sometimes a few liquorice hints, with just a little bit of sweetness. One that I look forward to smell when I get in the garden.

For those interested in hybridising, Desdemona is a good seed parent. It may have some residual self incompatibility as hand pollinated hips tend to have more seeds than OP (that have on average 4 to 5 hips). The OP seeds I germinated seemed to be self pollinated, though.
