I finally located a photo of an open bloom of 72-08-11 (Condoleezza X William III), mentioned last Spring in a blog post. Not much of a photo (low res from my iPhone) but you get the idea. This reminds me of 'Great Maiden's Blush' in color and form, and it has a decent fragrance as well. See the spiky mossing on the bud in the upper left?
I plan on working a few of this group of 72-08s into breeding this coming spring, assuming any of them have fertility. Who knows, maybe the Spinisissima genes will be a new resource for winter hardiness and disease resistance.
