I bought mine at Heirloom Roses - they have a website that you might try: http://www.heirloomroses.com/ If the rose isn't listed on the website - you might try emailing them, as they had several when I was there last week.
It is still sold by Delbard, and in their this autumn's catalogue. They send to Italy - postage 10 euros. There are no problems with them - I have ordered a lot of roses from them. This is the link for the website: http://www.delbard.com/ Just put 'Perle Noire' in the rectangle top right. Then,when you put the rose in your 'basket' just scroll down to Italy for the destination. But I bet you speak perfect French too!!
