Re: Gloire des Rosomanes - experiences

Kim (or anyone :) ). Would you recommend any particular roses that can "break" species dominance when crossing with species? Quite often when crossing species the offspring doesn’t defer all that much from the species parent. But of course my assumptions could be wrong. I've read some odd things wit...

Re: Gloire des Rosomanes - experiences

Thank you. There was an Orangeade X Fed seedling that flowered spring through fall, so it IS possible in the first generation. Plus, using something odd such as a triploid mini, you can obtain repeat in a generation. https://www.helpmefind.com/gardening/l.php?l=2.73780 I used that with Pretty Lady ...

Re: Rosa pomifera

Would that be the same one as R. Villosa ? I've that one marked as pentaploid with canina-meiosis. Did the offspring also inherit the slightly fragrant foliage of R. Villosa?

Re: Gloire des Rosomanes - experiences

Haha :) I've looked into the F1 hybrids of Fed. Turns out you are the man with most experience in the matter. You have some very nice offspring. This one is beautifull and with mossing! https://www.helpmefind.com/rose/l.php?l=21.302767 And this one: https://www.helpmefind.com/rose/l.php?l=21.168914 ...

Re: Gloire des Rosomanes - experiences

Fedtschenkoana blooms have the "Lindseed oil" scent, similar to Foetida. Foetida has been credited with having introduced the "fruity" scents into modern roses. I wouldn't worry about introducing any scent from Fed as it is already "in there" in Autumn Damask and that rose has a magnificent scent. ...

Re: Gloire des Rosomanes - experiences

I've checked my plant hardiness zone. That would also be zone 8 and near the North sea. Quite humid. Maybe similar to NW Pacific climate. I'll give primula a go, but with low expectations :)
Tx for sharing.

Re: Gloire des Rosomanes - experiences

The scent of R. fedtschenkoana you describe maybe leans towards the incense odour of R. primula? I saw one of the seedlings with quite some glands on the buds: 1-72-1DLFED7 It is striking how diverse the offspring of your cross is. R. fedschenkoana has the reputation of having flowers that do not sm...

Re: Gloire des Rosomanes - experiences

I wasn't aware that China's also had somekind of foliage scent. In Damask and Centifolia's the pine scent mainly comes from glands/hairs on the young leaves and flowerbuds and rubs off, but isn't "air borne". Is this the same with GDR and Grandmother's Hat? Or is it more similar to the foliage scent...

Gloire des Rosomanes - experiences

Does anyone have experience with "Gloire des Rosomanes" as a parent? On HMF I see: 16,335 unique descendants. And I see "fragrant foliage". Which fragrance would this be?

Re: Why keep parentage a secret?

I didn't want to point a finger at Austin, but he, and Ducher are the ones that spurred in my OP, because I was trying to figure out the parents of two roses I have. I've also stumbled into roses because of some roses I got obsessed about on identifying. Twice actually. First a botanical rose, then...

Re: Why keep parentage a secret?

won't touch The Fairy or anything bred from it because of its addiction to crown gall, which is an issue in my area. Drifts and Flower Carpets are all extremely susceptible to gall and literally die out from them after a few years in the ground. They are used extensively in my town and when I encou...

Re: Why keep parentage a secret?

I'm reading a book about a famous Belgian rose breeder (Louis Lens), recommended to me by Dane (thx mate ;) ) and it gives some insight on the matter. Maybe now it is less important than 80 years ago, to keep the parents of your best roses a secret. Back then al the big ones were doing crosses with ...

Thank you David, Karl, PacificJade for the valuable info.

Eva (Kordes) is tetraploid, coming from diploid seedparent?

I came across this rose: Eva (Kordes, 1933), a tetraploid pollenparent with a diploid seedparent gives tetraploid offspring. I didn't think you could hope for such a result. I'm assuming JC Thornton to be tetraploid at least. Robin Hood (hybrid musk, Pemberton, 1927) × J.C. Thornton https://www.help...

Re: Types of repeat-flowering in roses

It's been a long time since I visited the Heritage Rose Garden, but I seem to recall that Eglantine leaves are distinctly smaller than the Musk leaves. I assume with Eglantine you mean the Sweet briar (R. rubiginosa). I'd say the leaves are about the same size as the ones on R. moschata, maybe a li...
