Rosa rugosa progress

“‘Baby Faraux’ failed on me this year when put onto ‘Scabrosa’.”

Switch directions and weed out any selfs, if any.

Agreed: don’t use the Rugosa as the seed bearer. Find a good seed producing Poly and put the Rugosa on that.

Good luck!

I got R.blanda pollen to take on Marie Pavie this past year and have a about 16 seedlings. All the attempts took and I got about 10 seeds per hip. If were to try that cross again I would reverse the parents as I’m sure I would get many more seeds per attempt that way. I tried R.blanda pollen on La Marne and Robin Hood (not a Poly but closely related) in 2007 where few of the attempts took and none of the seeds germinated. One thing to remember is that Polyantha seeds germinate best at about 50 degrees F, so don’t put them in the fridge.

I also used three different Rugosas this past year as seed parent, though I didn’t use any Polyantha pollen on them. Two of them were very particular as what was put on them and most attempts failed. But Showy Pavement accepted all the pollen I put on it with 66 seeds per hip average. I also got close to 30% germination rate overall from them. The only drawback is that the seedlings are week. So if I were doing a Rugosa x Poly cross I would use Showy Pavement as the seed parent. With a Poly x Rugosa cross I would use Marie Pavie as the seed parent.

I would like to show a mauve-colored rugosa seedling from a German rose grower / breeder who has been sowing the OP hips of his rugose rose assortment for several years and selecting the very best of them. This mauve rugosa hybrid is one of his latest discoveries. I was grateful to be able to use this rose for hybridization this year and I harvested several rose hips from the young stock a few weeks ago. Especially lovely is, that this seedling is already blooming again, as the attached photos from yesterday and today show. The prevailing intense sunlight of the last few weeks (alternating with a few short rain showers) has lightened the color somewhat, as the mauve tone is normally even more intense. This breeding impresses with its vigor, exceptional health and amazing scent. The seed parent is ‘Rotes Phänomen’.

Very beautiful. Love the purple filaments and anthers. Thankyou for posting the progress report.

Looks like the petals fall free from one picture or were they helped? I am always looking for rugosas that do this easily. While not a rugosa, there is a close relative, ‘Albertan’ with 10 petals that does not ball. I imagine that it is 100% Rosa woodsii.

Thank you very much for your feedback! Sorry, I don’t quite understand what you mean. The rose was
photographed exactly as it grew and developed. I have attached another picture under a different viewing angle for you.

I was asking if the petals fall freely or if it balls a bit and needs help cleaning them up. There is a photo with a spent flower that was nice and clean -no dead petals hanging on. I was wondering if it was you or the plant that got it that nice. Thank you for the reply. What ever it was you have a winner! Johannes

Thanks again for response. I have now understood your question. The petals fall freely and do not ball. This rose cleans itself very well.

That is what i want to see hear! Have you released it?

Unfortnately no, because it is not my own breeding work. As I mentioned at the beginning of my posting, this rose seedling is the success of an established German rose grower who selects the best seedlings from the OP- rose hips of his Rugosa rose stock on the side and then sells them himself. I used this creation for my own breeding this year. Since I think this rose is interesting overall, I just wanted to share its existence with the community.

It’s been released by the breeder and is available from their nursery. Along with some other interesting Rugosa by the looks of it.

They have a fair selection of Rugosa both new and more well known.

I’ve added Wild Eagle to my garden this season. And if I can make room I can see me trying a few more of his varieties.

Ah, rugosas. So sweet, so hardy, so frustrating.

My first problem is iron chlorosis in my high pH soil. They seem to always turn chlorotic.

Then you start crossing them with modern polyploids and the results are just…weird. And usually sterile.

Henry Hudson seems to give interesting offspring. I had some OP seedlings that looked like an extra-vigorous wild rose. Eight feet tall and thornless. I can’t figure out what the heck the pollen parent could have been. Unfortunately got grubbed out.

Ralph Moore had several greenhouses full of weird, once-to non-flowering, prickly, enormous, rangym chlorotic seedlings from Rugosas. He felt his problem breeding with Rugosa was due to using too little pollen, so quantities were increased and eventually, pollinating on successive days were tried with success. Even more weird seedlings.

Have you seen it in person? From the pictures it looks quite red.is this the case in real life?

I have found that I can obtain the parent or this beautiful rugosa in the UK, which due to the colour/repeat/scent is very interesting! Apparently it’s damask with spice!
