This rose is bullet-proof. Survived Houston drought summer 2011. Tried to dig it up once - the roots were so thick couldn't even dig it up! I cut it back to the ground, and it grew back very fast with large clusters of vibrant pink blooms. Bloomed all winter. After seeing this - I want to get another one! Very disease resistant and never balls in humidity.
And, it roots like a weed, growing perfectly on its own roots. If you have prunings of it available, they should keep you supplied with cuttings as long as you want to keep rooting them!
Hi Margaret, I don't grow Otto Linne, but the rose in the photo you posted doesn't look like my Excellenz von Schubert nor the EvS plants I saw at Eurodesert last year.
I acquired a leftover stem of Otto Linne from the Santa Clarita Valley rose show this weekend. I will try to root it and see what happens. It’s a graceful beauty.
It is interesting that the Proof of the Pudding featured 'Gartendirektor Otto Linne' in 1937 and 1939. And then another 1938 reference mentioned the rose was "well thorny". In the sixties the Proof of the Pudding featured it again and said it was "nearly thornless". Why would the Pudding feature it 27 years apart.
I would guess that the true Gartendirektor was quite thorny, as described in the 30s. Then it got lost and was "identified" in the 60s by someone as a rose with few prickles.
