Thanks to the fabulous "Vivaio la Campanella" Nursery I identified the blooming rose I have posted this morning.
It is a Aimeé Vibert a Noisette climber, introduced by Vibert in 1828.
Everything matches, the type of blooms and the fact that it is a late bloomer in June followed by a second flush in September.
Sweet scent and a fairly resistant rose.
Some say it grows up to 3 m but I think it can do much more than that, since mine is grown in a pot and is already that high.
Alternative names: Bouquet de la Mariée, Nivea, Unique

They are real pros!
