Rosa roxburghii (Double Chestnut Rose)

I got this rose from a friend a few years ago. It is a very unusual rose. It has spines on the sepals and hips, has up to 13 leaflets, has exfoliating bark, and one thing I forgot to mention in the video, its prickles (thorns) come in pairs at each node and stick up. The bloom is an unusual cupped shape with many petals, a button center, and a nice old fragrance. I never have to spray this rose! That, and the fact that it blooms periodically through the summer and is so different is why I love this rose.
