Rosa rugosa X 'Double White' Scotch Rose

Here are two from a cross of rugosa with ‘Double White’ Scotch rose. I was hoping to get something like I’d gotten from a previous cross of rugosa with spinosissima, only with double flowers this time. Well these aren’t double, but still very nice and darker than the batch from before with pollen of regular spinosissima. Those original ones haven’t ever set a single hip. As you’d expect, they are once-bloomers and sucker enthusiastically. I really need to explore the possibility that they might have some degree of pollen fertility.
