Interesting rose. Would love to see it as a mature plant in the ground. Foliage, buds, and bloom remind me of something halfway between a silvery mauve miniflora (like Sweet Arlene, for example) and 'Trier'.
Edit: Ahhh, not too far off. One parent is a purple floribunda bred from minis, and the other parent is a modern rambler, with small, semi-double Dortmund-like blooms.
I'm growing this rose, it's slow to get going and likes getting fed (greedy wee thing), but it's blooms are lovely and it has the most unique and sweet fragrance.
