What about Snow Crystal? That one caught my eye. I haven't looked at price on the LA or even if it's listed, trying to behave myself as all planting spots are spoken for already this year. Know nothing of it's fertility either, I just really like the form of the flower.
Searched my plant list and found a few more images to add...

Rock Solid, an excellent garden plant and wonderful parent!
Rose Corsage
