I keep my fingers crossed Jon.
I already had seedlings from one seed from one hip.
Its a try! Good that you have at least ONE, so you know it COULD be a good idea, what you did (that keeps your fire alive).
Grx!

Hi!
That what it looks today (I will post the next update in a week or so):
Grx!

Hi!
Here is the seedling of Rosa stellata mirifica x Veilchenblau again. He shows now his 4th and 5th true leaf, the 6th is underway. …
On the fotos you also can see the labels from other seedlings in my “zoo of odds”. 
This is a little part where I plant all the seedlings that should in fact not be alive - although they are. 
And here nearer to the 5th true leaf:
The question remains: is it or is it not? I would say the leavlet forms and the serratet leavelets are a sign that it is a true hybrid.
But still it is very young … .
Grx!
Arno
As nobody suggests something I come up with this:
It must be a hybrid because of the stems of the leavelets, they ar much longer than it is for the typical leaves of stellata mirifica, especially in the last picture.
You can see increase the lenght of this last middle stem, from the first true leaf to the 5th!
Grx!

Hi!
I will report the further development of the crossing (and next upcoming seedlings of this and other hybridizing lines) more often also here:
and more often here:
http://www.rosebreeders.eu/forum/index.php?topic=126.0
and for Hybrid Hesperrhodos seedlings in general here is an overview where they appear:
For a broader discussion a broader a bit wide spread input and interest this might be better. Its not a theme for the masses, I know.
For me it’s always been a delicate theme and I want to have simply more input and discussions, - as much as possible. …
In the RHA Forum I will post news from time to time, especially for the first flowers or my further germinations with Hesperrhodos. …
Jadaes input and thought exchange here is always great, thanks for that.
Grx!
Arno

… and here, too (only in german language):
I assumed that the hybridity was implied, so I didnt say anything lol.
Hi Jadae,
even implications can be wrong, but a wrong thing - not worked out as wrong by arguments - still stands there as being right.
My arguments can be read here, less further came up, so yes, it has to be a hybrid … . ))
Now, seriously spoken: My first hope was, that someone with good experience would give a comment here, whether it looks like stellata or a stellata x hybrid.
But the plant will develop, lets see. …
I think the flower then should be easier to interprete. …
:-X
Grx!

I think it has to be a hybrid. I grew several op seed of stellata this spring from mail order seed and these definitely deviate from the form. I however do not know what version of stellata the op seed is from. But here are my reasons for you having a hybrid on your hands. 1. the leaflets of these seedlings are much too spread out (the stellata seedling I have growing the leaflets are more compacted together) 2. the terminal leaflet is quite a bit larger than the side leaflets (on the op pollinated seedlings it seems that all the leaflets are about the same size giving the name gooseberry rose an easy description on your photo from june 20 the first true leaf looks the closest to what I am talking about) 3. the petiole to the leaves look longer (the op seedlings i have growing the petioles are very small) 4. while I can not see them that well in the photo it does not seem like your plants are super thorny (every seedling I have is super thorny they are covered from head to foot with long straight thorns that do not curve on bit and the thorns started to appear about in between the time the first true leaves and the second true leaves showed up.) With all that said however I do not know the form that I do have so I may be wrong in my thinking.
kathy the R. minutifolia is already starting to bloom. It has put on a great deal of growth already. And has 3 flowers already bloomed and is putting on some more. The leaflets are extremely small and I noticed they smell which is nice. It is a very thorny plant like R. stellata seedlings I have growing right now.
Oh by the way my main interest in these two species is for drought tolerance. In the summer it is hot and dry here and the winter it is very dry. More plants are lost due to drought then to the actual cold. I figure if R. foetida and it relatives do well here maybe that is a clue to me. I figure I can pick up the drought tolerance and add in winter hardiness and see what happens. I also what to see what else is in these roses since neither one has been used that much. I was surprised at how well the R. stellata seed germinated. I do think it has a inhibitor in the seed coat that needs to be leached out first. By the way R. stellata seems to have some powdery mildew resistance very few of the seedlings where infected even when the majority of the seedlings in the trays around them were covered.
Hi Adam!
Thank you for your detailed thoughts on that topic.
Your lots of details are a good summary of several traits that may be of interest for everyone who will hybridize with stellata in the future.
The type of petioles and leaf form are major traits that can be seen here, I also think. And: the prickles at the stem that you mention are really there.
And yes, I also think that there is at least some powdery mildew resistance in R. stellata var. mirifica.
The seedling above e.g. is (as described above) still healthy after over a month, what is unusual for multiflora seedlings.
For your drought problem I might have an idea.
What about Rosa beggeriana crossings? Kruessmann writes its difficult but that is all relative to what you do. …
I have some F1 plants out of a 2005 species cross that sparsely flowered for the first time tis year. I immediately did a cross between the F1 at 4th of June to get a spreading of traits in the F2.
One out of five hips did take very well!
And beggeriana is not only drought tolerant but also very winter hardy.Additionally it flowers over a very long period until autumn.
I love that rose, really, and can only tell you that it might be an interesting perspective for you.
Grx!
Arno
I will have to keep Rosa beggeriana in mind. I am very interested in all kinds of species anyways. If I had thousands of years in which to breed something and unlimited space. I think I would start out with nothing but species and breed them just to see what I would end up with in the end.
Hi Adam!
If its possible in any way I could send you material of my Rosa rugosa alba x Rosa beggeriana seedlings material.
I could do cuttings, seeds is a bit diddicult aat the moment as there is only one hip that produced seeds.
Grx!
Arno
PS: mirifica x crossings are doing well. Info following.
Should be “a bit difficult at the moment as there is only one hip that produced seeds.”
TreasureTrove that is a nice offer but I am still trying to figure out how to do cuttings. They are probably safer in your hands. Maybe I could get pollen from you next year instead?
I have done one cross of Ann Endt x R. minutifolia this year. Hopefully it and the other few crosses on Ann Endt matures before fall. The crosses where done last week. I do not know if they will mature in time or if they will take.
Hi Adam,
OK, I will try to send pollen, I only don’t know how to send it in a way that it is still alive if it arrives. But we’ll work out, there is a whole year until then.
Next year the plants will flower much more that this year, so the amount pollen is no problem, only the long shippement and so the viability of the pollen, when it arrives.
I use small Eppendorf Cases.
Grx!
Arno
TreasureTrove most people who have sent me pollen have sent the dried pollen in a folded piece of paper that is taped together and then put into the envelope that way. It seems to work fine. Most of the time the fertility is fine. Those that have not been that all fertile I still managed to get a few takes and maybe the fertility on those were fine but I crossed them with the wrong thing.
While I am talking about pollen Joel I need to here back from you on what short of things you have and what direction you want to go, so that I can collect something that will work for you.
Adam!
They are remontant! Today I spottet a couple of flowers on three of the bushes! One flush in May and one in August!
I will open up an own little thread for them here. A wild rose crossing with a remontant feature … .
And very winter hardy - and droght tolerant too … .
This is quite cool.
Grx!
Arno
The F1 seedling of Rosa stellata mirifica x Veilchenblau is still fine, he did not grow in July but since two weeks or so it had three more leafs.
Always still of three leaflets so far!
Grx!
Arno
I do believe my minutifolia has died:(
\
The seedling from my crossing with Veilchenblau is alive!
It did survive winter 2010/2011 here in Germany and begins slowly to grow!
By the way: The stem is less than 1mm thick!
Grx!
Arno
