It looks like you live in Italy, but most of us on this forum live in the United States, a few in Canada and a few in the UK.

Different rose varieties may be available to you than there are to us.

Is there some way you could find out from where you bought it what variety of hybrid tea rose you ended up with?

As far as I remember (because I've been there just the year before) the package was from a company from Slovenia and i bought it in a big shopping center here in Italy, but I don't remeber the company name. I bought 3 roses there: Brandy, Buccaneer and the 3rd is the one to id.
Could it be a Hot Pink Lempicka ?

I already checked two books with over 2000 roses, this colour is not common it tends to mauve, I exclude the Hot Pink lempicka (wich is too coloured), I thought of Nil bleue but maybe it's more a Mauve Melodee according to the foliage and flower colour. Brandy and Buccaneer are US patented roses therefore I believe this should be too. The only roses I see they sell all around here are English and American tea roses!

It reminds me of Heirloom... although the petel count looks like it may be lower....
