This seedling doesn’t mildew. A lot of its siblings, however, do. My main beef with this seedling is that it seems to be stingy in the foliage dept. I’m hoping that will change as it matures. There are really good ‘Temple Bells’ seedlings coming through that are about to flower too that might work well into this project. Even ‘Temple Bells’ itself would be awesome… it’s so fertile you only need to put pollen near it and it will set crossed hips. I have ‘Temple Bells’ x ‘Anemone’ seedlings coming up too… duds all of them. Will try with straight laevigata instead.
As far as clinophylla plants go, I have about 80 seed raised seedlings. If anyone in Australia would like to try working with it you can send me a pre-paid post bag and I’ll send them out. Quarantine doesn’t seem too worried about it so I’m over worrying about it too…

“Should I even bother applying pollen to my R.clinophylla given it is flowering for the first time in its life?”
Why not… life’s too short too hedge your bets 
If I use these few flowers as hip prospects, I will not utilize any of their pollen, as I have been under the impression that emasculation on bracteatae spells trouble.
So if seed parenting is doubtful in my situation, then I would rather use all of these (limited) flowers as pollen donors, only. But if seed parenting is likely in this case, I would definitely prefer to use it as a seed parent. This is the reason why I am asking.
So, which way have you used your R.clinophylla flowers Simon?
…or if you don’t have any flowers yet on your R.clino, which way will you prefer to go with them when they flower?
Oh yeah… while I think of it…
I am real interested if anyone has a little time to explain here what the pros / cons are of breeding with clinophylla versus bracteata in their own breeding experience. That would be REALLY appreaciated.
No flowers yet… my focus to start with will be plant it in the ground and leave it for a while to watch it and see what it does and how it behaves… never know… might be like laevigata here and never set a hip for us. The next goal will be to work on something diploid and fertile. This is why I’m thinking 0-47-19 seedlings, but I have also got ‘Immensee’, ‘Temple Bells’, hundreds of ‘Temple Bells’ seedlings, and the flower carpet roses to play with to dabble with higher ploidies as well. I’m loving the idea of getting it together with ‘Trier’ atm and even persica if I can ever get anything to germinate from ‘Euphrates’ and the better Teas, such as ‘M. Tillier’ are going to feature as well. Lots of paths to follow. I think getting to tetraploid will be a goal somewhere down the track though at this stage I’m not totally convinced just yet. Next goal will be to get it into shrubs of various sizes. I see the Teas and Chinas playing a role here as well as some of the better minis, like ‘Little Wonder’, and ‘Snow Carpet’. My OP ‘Baby Love’ seedling will play a part because it is completely unaffected by mildew or black spot at this stage. I’m going to go in lots of different directions though so will just wait and see.
George,
I seem to recall that the R. clinophylla seedling shown in that HMF link bloomed for the first time when it was one year old, but as I grow several thousand seedlings every year, remembering every detail about every seedling isn’t always possible.
Simon, maybe I’ll pick all these few flowers for pollen, and if it DOES flower more later on, I can afford to experiment the other way. Truth is, my other prospective seed parents that could accept this pollen are also young plants, all planted a few months ago…lol…so it is a bit of a quandry…wateva o_O
Paul, thx for the extra bit of information, it does help me get a grip on the time required to develop newer generations beyond F1…alas, time is our greatest enemy.
It goes without say that you can also have this R.clino pollen now if you wanna play with it Simon.
Thanks George, I don’t reckon I’ll be too far behind you with 80 odd plants to push along I’m focusing more on laevigata and gigantea at the moment… they are flowering and I’m freezing pollen to use later in the season.
Update:
My OP R.clinophylla and (the more compact) OP R.clinophyllaXbracteata plants have both universally rejected tetrapoid pollens…I am not really surprised, I know it is a lot to ask of these relatively young babies!!
I am going to switch over to using both of them as pollen parents for now.
To my amazement, both are repeat flowering very nicely.
I really love the fragrance of the pollen, it is particularly potent when you sniff it as dried pollen in a jar…Viru suggested this could be done as a test for clinophylla parentage if clinophylla hybridity is in dispute about a seedling…Thanks Viru!
Viru described to me the clinophylla pollen odor as being similar to acetone-like. Concentrating this pollen in a jar gives the fragrance great potency+++, however the actual flowers on the bush have only a delicate hint of the same sweet fragrance.
The seedling to the left is my OP clinophylla X bracteata, the larger one to the right is my OP Clinophylla. This picture was captured using a mobile phone camera this afternoon. The fence in the background is a bit shorter than the height of an average person:
Both these seedlings were germinated by embryo culture within days of each other in mid-late January 2010, which makes them both 11 months of age.
Next time I get close to them, I’ll try and capture some close-ups and hopefully flower shots.
George,
For 11th month old seedlings they look good. Wouldn’t expect a HT or even a modern shrub to look as good, LOL.

Hi Jim P.
These species/species hybrids are thriving in my climate, they also seem quite tame/in bounds, at least so far in their lives.
The other OP R.clinophylla seedling I had, I pulled out several months ago, as it was was showing some definite PM on the canes and leaves as well, causing some minor disfigurement. I kept the one in the picture, as it was the better of the two in this regard. It still shows no leaf PM at all…It does have a curious whitish appearance of the young cane tips (not the leaves)…I am not sure what this is, but it actually looks “cute” and is of no consequence whatsoever.
There is no BS on either specimen shown, which is amazing for my hugely BS-infected rose garden. Most of my other modern roses have already lost at least 25% of their foliage to BS, some a whole lot more, which is quite typical round here!
Update:
Both my OP.clinophylla and OP.clinophyllaXbracteata specimens are now showing very occasional patchy powdery mildew on the larger thick canes, in sections that are against he fence and getting hardly any airflow. But the problem is entirely minimal. There is also some “spotting” in a very small percentage of the very oldest yellowing basal leaves (say like 1%).
This is the coolest and wettest summer we have had in a while…it is a very comfortable summer, at least to my liking!!
I am very happy with the performance of these species in my climate, so far they continue to thrive, are fully foliated and green, and look extremely healthy!
No disease at all, but the little bugger is scaring me! I’ve never had it tip root before. Minutifolia tip roots everywhere it gets a chance. I guess turn about is fair play. The Clino-bract seedling is rooting in the Minutifolia pot! I know of two tip rooted pieces, there may be more. Might anyone want a start of it? This is the “runt” of the litter Robert shared with me years ago from Viru’s material.

Oh… really??
My most favorite method of air layering plants (there are numerous ways), is to bend down and thread a long enough cane of such plant through the drainage holes found on the bottom of a plastic pot (or else make a hole on the side of the pot and thread it through there), and then I fill the pot with garden soil, until only a small bit of the cane tip is left open to the air…even the most recacitrant types of plants that resent rooting as cuttings, will root if you do this to them!!
Anyways I did this last week to both my clinophylla and my clinobracteata, just in case the originals die…and from what you say, I expect to have rooted copied in no time!..great to know!
Good to know to prevent unwanted ones, too! LOL! Kim
