Ooh, you have a really good shot there! I never seem to get out back, with a camera, when the wilds are blooming. Too busy in the main gardens then, they just slip my mind. I don't think mine have a scent though, it's hard to tell since they bloom at the same time as a wild shrub that has a really strong, sweet smell. Maybe some kind of Russian Olive?
I've never taken pix of the shrub, it's only pretty by its smell, the visual aspect is that of an ugly duckling. Serious. Thorny too.
....and yes, the birds bring those wild roses everywhere!
The birds like to try to nest in my gutters, if I don't keep them cleaned out in a timely fashion I even get those roses sprouting up there! Imagine!
