In the description, the wrong rose is mentioned: "This is possibly 'Princesse d'Esterhazy', a hybrid china bred by Hardy"... but 'Princesse d'Esterhazy' is a noisette bred by Cels.
I think that here is meant 'Prince Esterhazy' the rose bred by Julien Alexandre Hardy:

... But that-ones colour is wrong.

The rose of rosaplant seems to be a completely different-one, than De Bierkreek sells.
See the photo's of Rosaplant of their own and the photo, they made at De Bierkreek.

This rose (that is almost scentless), at least the one in commerce as, lasts more than 3 weeks on a vase!!!
It would be wonderfull in bouquets, such as Little Biedermeiers. See:

In the description, there is doubt if the breeder is Geschwind. Others say that Geschwind never bred a rose named like this.
Is there any-one that knows what is correct in this matter?
