This is the oddest rose I've ever known - I've had it in my garden for nearly 20 years and I still don't understand its habit. Luckily I do have tons of room for it - I placed it in a fairly undesirable location out along the road (shady most of the day other than mornings, no supplemental irrigation) and it's gotten very large with stiff octopus canes that nearly reach into the road. It is interesting that each lateral produces a single flower on a long stem, which must be why it shouldn't be pruned or deadheaded - you'd essentially be cutting off all the laterals!
