Definitely grown to the top of my roof now, and that is about 900 cm from the ground. Growing on east and north side of the house, blooms very well in part shade.
How is this a hybrid multiflora? =/ Hybrid Synstylae, sure. Hybrid Soul., definitely. Hybrid Mutliflora, definitely not.
Ive seen some rebloom on this rose even during the summer in Oregon. Its probably among the prettiest ramblers Ive yet to see. Its a pretty plant, too, as far as ramblers go, which are usually not very pretty plants.
