This rose is now close to 8' high and 6' wide in a 15 gallon container rooted into the ground with plenty of moisture here in my very warm semi-tropical low desert climate. It's going on 4 years old from seed and flowered the second year.

After speaking to Mel Hulse and Cass Bernstein about cuttings of this seedling I shared with them, I learned that clinophylla is making very slow progress for them in the San Francisco Bay area. This species apparently needs heat to thrive and is relatively tender to cold..

New hybrids developed from this species were featured at the Great Rosarians Lecture at The Huntington Library and Botanic Gardens January 22, 2006.

Clinophylla was removed from my garden in 2007 after it achieved a height of approximately 20'. This species was extremely vigorous for me and set viable seed. Some tendency toward Powdery Mildew was noted in areas of restricted air flow.

Clinophylla/bracteata hybrids hold great hope for those of us gardening in the South who appreciate roses that endure heat and flower well during our mild Winters.

It took -10 centigrade here last year with no damage but does get the Heat (35-40C)

John, did clinophylla retain it's foliage at -10 C? Thanks, Robert
Reply #3 of 8 posted 26 JUN 10 by John Hook
to some extent it retained its foliage maybe 50% but no damage

Thanks, that's good to know. I'm working on evergreen derivatives.

The Hybrid Evergreen Gene stood up to the same temps with no foliage loss

'Evergreen Gene' was beautiful here but Viru tells me it has been infertile for him.

Have you made any clinophylla/bracteata crosses? I think I already know the answer hehe. You probably have made 150. :)

I never did this cross but Viru did. He and Girija disseminated quite a few op seed to hybridizers world wide.

I have descendants through Ganges Mist.

Every occurrence of this rose I have come across has been 'General Ganiviat'. I would expect the true form to be along the lines of 'Lady Ann Kidwell'

Professeur Ganiviat?

There has been speculation about "Camnethan cherry-red" as a true Princesse de Sagan.

Yes - most of the photos here seem to be 'Professeur Ganiviat'.
