No, I bought Surbrunnsgatan from Martin Weingart in 2002. In 2003 I took cuttings from that unknown Hybrid Perpetual I've found in Biburg. The owner, a 74 year old woman told me that the rose always has been called "Hofrose" = "farmrose". It was already in the garden when she moved to the farm after her marriage, 50 years ago. The first time my cuttings bloomed I was very surprised. They remembered me of Surbrunnsgatan. To become sure, I planted my "Biburger" rose next to "Surbrunnsgatan". Since 2006 I'm watching these roses and I cant find any difference between them.
