Beautifully & completely covered a 7ft rebar tripod trellis by second spring. Easy to grow. Very lush, elegant foliage when not in bloom. Blooms perfume the air. Heavy feeder...grows best with manure. Healthiest in full sun. Laterals snap off the moderately flexible canes VERY easily on this rose. Take care when training/moving/prunning. Minimal blackspot in late humid summer. (I don't spray this rose until then)
if you mean, that the desease shows rather on the young buds and penticels than the foliage i would say yes. (mine shows the same symtoms as "viridiflora")
