The early Australian references (1956, 1957 and 1958 etc) referred to Titian as being a tall-growing shrub.
In 1962 Mr. Kordes was writing in the Australian Rose Annual “Titian is still a very fine variety, especially for Germany, as our people are very fond of double, tall growing roses”. However, he listed it in his 1964 Roses book, mysteriously quoting a height of 20 inches , [as did Krussman in 1974 who quoted 16 inches]. I feel that there may not have ever been a Kordes ‘Climbing Titian’ sport, but perhaps when these little plants got into some good German soil, it remembered that it really was a tall-growing pillar/shrub rose. Is there any hard evidence of this 1964 Kordes ‘Climbing Titian’?

Frank Riethmuller was a constant correspondent with Kordes (in German). Refer Breeder > Riethmuller window.
