Kind of a unusual sweet fragrance to me, makes me think of marshmellow, something kind of powdery. It's a strong pleasant smell, just not something I've smelt in roses before.

Is seed fertile, not exceptionally but not difficult either.

Update on fragrance, its something akin to Centifolia, similar to crested moss.
