I have heard from some who grow this rose, that the fragrance of R.clinophylla flowers (as well as its dried anthers/pollen), is acetone-like.

It's not quite that bad - bananas and oddly chemically. Acetone is too strong a scent: women associate the smell of nail polish remover with acetone, and Clinophylla shouldn't be associated with an odor that strong or that offensive.

Actually they are included. When a site user posts a COMMENT to a rose page, that comment is archived and will always be attached to that rose page. Unfortunately, many site users do not click either the REFERENCES or COMMENTS tab on the rose page and miss some very good information provided by the rose community.
Fragrance is often variable and it would be almost impossible to report all of the descriptions of the fragrance of a rose. That's why it is very beneficial for people to share their experience with the roses they grow.

I don't get acetone, but I can see how the camphorous note may be chemical like. Cass mentions bananas, which is somewhat close. I smell Juicy Fruit gum and almond layered with eucalyptus/peppermint. It's a pleasant & unique fragrance combination that should be further explored in hybridizing.
The plant @ SJHRG is now about 8 feet tall by 5 feet wide. The fountaining growth pattern and short flower stems along every leaf node reminds me very much of the grace and delicacy of R. hugonis or R. cantabrigiensis. In early March the silvery hair covering the plant reflects the light and lends a downy softness like lamb's ears. In the heat of June the leaves look more wrinkled and folded, while the down has retreated to the tips of new growths and sepaled flower buds. Not much presence of blackspot or rust, but there might have been some mildew; however, my memory could be mistaken. The fully open, single flowers are 1.5 - 2 inches in diameter, in a warm white or ivory color, and crowned by a large, golden, candelabra like boss of stamens. The flowers blow quickly; therefore, pollen is best collected when the bud is just starting to unfurl, and the petals are still twisted in a flesh colored cone.

The scent of ripe bananas is isoamylacetaat. Angry bees, or those that allready stung excrete a similar scent, to alert other bees.
During the riping process it exudes ethyleen. Ethyleen is used to ripen unripe fruits(and bananas)
And yes, it is a bit like aceton, but not that strong and intrusive/pushy.

Has anyone smelled this rose at night? Not all white flowers are nocturnal, but I've been wondering if some white flowered Rosa species might be attracting some night critters.

Not quite night night yet but just past sunset (but can still mostly see without a torch if that makes sense) and it's very mild and inoffensive. The flowers close up at night though so nocturnal pollinators would be "locked out" as it were.

Thanks. That's what I'm looking for.
I read just yesterday that Rosa arvensis is reported to be "scentless by day but sometimes having a faint scent, just discernible, at dusk in warm weather."
It would be helpful to have more info on the pollinators of wild roses.

Have you seen bees hiding in the flowers at night? That has been reported for R. bracteata.

No, but I haven't really paid much attention to it. Of note most of the bee's I see around here are native types (like Blue Banded bees) rather than euro/asian/african honey bee's (which have some monitoring and control over if feral hives are reported) which may influence that.

What's the key difference between this species and bracteata?
|
REPLY
|
|
Bracteata leaves are deeper green, thicker, glossier with a much heavier cuticle.
It is reported to offer mechanical resistance to RRD. I'm not sure clinopylla has ever been evaluated.

"mechanical resistance"?
|
REPLY
|
|
The mite can't infect due to thickness of the cuticle, etc., not because it's genetically immune to infection.
|

oh I see. Yeah. I really like the idea of a nice thick camellia like glossy leaf with a little rugose ridging. Maybe even some dark pigment. Bugs and predators hate tannins and anthocyanins in leaves. It makes them taste bad and they are harder to digest.

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

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.

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.
