The author [Friera] adds the following data:
Retaing the same features as the Spanish variety, there is a Climbing Duquesa de Peñaranda, a sport released by Germain Seed & Plant Co., of California, 1940.
....This is a hybrid tea with perfectly pointed bud, when expands becomes a charming, but messy bloom. ....although it holds the Mediterranean heat well, lasts very short and matures quickly. ...has an acceptable repeat, but is not a rose which blooms in masses. Unlike other Pernetianas, not very susceptible to fungal attacks....The name refers to the Duchy of Peñaranda in Duero, Burgos...
