Does anyone have any experience growing this rose? Despite having the coloring of the faded maroon velour seats in my grandmothers 70's Buick Regal from when I was a child, I've come very close to ordering it own-root from Roses Unlimited. The ARS rating on it is fairly dismal, and they are spot-on with their abysmal rating of Blue River, so I've been hesitant to give her a try.
