I know very well that some rose bushes can be genetically mutated to produce a 'sport' climber. Or any rose bushes with tall or long canes especially DA roses can be trained as a climber
In DA's web site they sell bare roots of some roses (the same rose) in both shrub/bush or climber form.
So my question is - are these so called 'climbers' sports of the shrub/bush variety? Or it is just how they present or shape/prune the canes on the bare root?
Most of their so called climbers are labeled to 8-10 feet. I understand in warm areas, the same rose variety in shrub/bush form can grow as tall as 8-10 feet as well. So what is really the difference between the two bare roots? I can't find an explanation in their site.
Thanks!
