    HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

    Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

    We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

    Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

    We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

    As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

    RoseRosa clinophylla Thory
    Initial post 23 JAN 06 by Robert Neil Rippetoe
    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 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.

    RoseRosa clinophylla Thory
    Initial post 3 SEP 07 by Cass
    Rosa clinophylla is now in the ground after a slow start in this part of Zone 9a with occasional Zone 8b winter weather. It has been blooming continuously since June and shows no signs of stopping soon, as it is still covered with buds.

    In my view, a species that blooms from June into September could be called continuous blooming. It does not, however, appear to be setting viable seed, and I wonder if that might be extending the bloom season.

    Cass, the clinophylla clone you grow set prodigious quantities of viable seed in the Palm Springs area. Clinophylla had a long single blossom phase for me. Few if any have ever grown this species in a climate like yours. It very well might be nearly ever blooming there.

    I suspect the lack of fruit might be attributed to size and lack of maturity . My plant didn't start setting seed till it got fairly large.

    It is now the end of October and Rosa clinophylla is still blooming. After 5 inches of rain, it is producing new basals.
