I bought some roses from Dickson in Ireland in 2009 and I just wanted to say that I am very glad I did. It actually started with Tintinnara, which I had bought from Fryers in England. Then I found out that it was actually a Dickson rose, so I decided to visit their site and find out what else they had. My, my, they have some very beautiful roses! Unfortunately my garden is filled up now!
On their site they also describe the breeding process, very interesting.
