These roses remind me of the wild roses that grew in my grandfather's pasture when I was a kid. We all played baseball (often it was bounce-out) in the pasture in summer, from oldest to youngest. Just to show you how pastoral this was, we used cowpies for bases. And wild roses grew all around. I don't think black roses occur in nature; ours were pink and white, but they were the same shape, with just one row of petals, just like these.
