Oh my that is breathtaking!!
In need to grow such beautiful roses, I love the fragrant ones!! All that is growing here are the wild varieties, which are fragrant in early spring.... but long gone now; awaiting the hips that can be harvested after the first frost. seeds of the rose are found in the rose-hips, btw
Although many roses are hybrid varieties.
The wild roses are definitely open polinated reseeders, and are often spread by birds...
