Re: Rose seeds for sale this spring at a box store!

That's definitely interesting, and unusual to find with R. rugosa seeds inside. It would be disappointing if the results don't match the expectations. The cynic in me wonders if they're banking on none of the seeds germinating, so no one will find out that they aren't actually miniature...

Re: Magic elixer for creating interspecific crosses

To the last paragraph: I wouldn't think so, unless somatic hybrids are also considered to be GMOs. Both processes merely involve lowering or bypassing the usual natural barriers to interspecific (or intergeneric!) hybridization in some way, but somatic hybrids are not regarded as GMOs. If the proces...

Re: My Yellow Hybrid China, Champagne Bubbles

Your photo of the bloom reminds me of 'Safrano'; it would be great to see a modern version to that (large) workhorse of a rose, as much as I enjoy it. That looks like a very nice result.

Re: Alternate source for repeat bloom

Maybe. You do have to allow a bit of license in such descriptions (and while the protologue is important, it's not as important as the type specimen, if one exists); more critically, the Latin term used to describe the abaxial leaf surface doesn't really translate as 'hoary' but rather 'canescent' (...

Re: I. D. of hybrid spin?

I agree with hjortur--'Nevada' is an excellent suggestion. I haven't been able to keep young plants alive very long here due to its disease susceptibility in my climate, but I did get some flowers first. It has a wonderfully sweet perfume, far better than that of 'Fruhlingsduft', in case that helps ...

Re: I. D. of hybrid spin?

Yes, the fragrance can be quite pronounced in these hybrids--I'm most familiar with 'Fruhlingsduft', which has a mixture of that linseed oil odor and a sweeter fragrance that is obviously the reason for the name. I would not call its scent entirely pleasant, but then I'm a bit sensitive to the sligh...

Re: I. D. of hybrid spin?

It reminds me more than a little of one of the "Fruhlings..." series. For what it's worth, I've long believed that they (the ones I'm familiar with) were not actually bred from a form of R. spinsoissima at all, but something more akin to R. laxa.

Re: Alternate source for repeat bloom

David, thanks, that is great to know--maybe the study that Dane mentioned above simply couldn't distinguish between the RoKSN A181 and G181 alleles, then? Otherwise, they may not have used a correctly identified R. moschata. If they vouchered and photographed the plant they used, it would be easier ...

Re: Scandinavian Import ID Challenge - Needle in Haystack Quest?

Hmm, that sounds hopeful(ish), but only 10-20 petals, can that really be right? They also give no indication of the rose being so different from most other R. spinosissima derivatives in looks; this one is so clearly distinctive in appearance (especially foliage/hybrid character) that you would thin...

Re: Alternate source for repeat bloom

If R. moschata truly did have two copies [note, prior to edit I had said "one copy," but then I read their supplementary data] of RoKSN_WT as the linked study implies, then there would have to be something else that is permitting its nearly continuous flowering (assuming their R. moschata is correct...

Re: Alternate source for repeat bloom

I think it's a mistake to assume that Rosa moschata has KSN_wild. 'Champneys' Pink Cluster' (which was the original cross between R. moschata and R. chinensis 'Old Blush'; it has been shown that 'Blush Noisette', which was a seedling of CPC, had some unidentified other rose as its pollen parent) got...

Re: Rebloomers genes

Sorry, I meant to indicate that I used the white-petaled, single-flowered R. rugosa (R. rugosa Alba Group, not R. x alba), as seed parent; 'Mutabilis' was the pollen parent. I generally find China and tea varieties much more difficult to germinate than R. rugosa, which also produces significantly mo...

Re: Rebloomers genes

I have a couple of seedlings from a cross between R. rugosa Alba Group and 'Mutabilis' that flowered for the first time in 2020 (the cross was performed in 2017) with an extended bloom time (at least 4/21 to 6/31), but the extension seemed to be due more to protracted flowering from long laterals pr...

According to the International Code of Nomenclature for Cultivated Plants, the identity of any grafted plant is that of the scion, not of the rootstock.

Re: Petite Knock Out Rose - AVOID

If that's true, then the only viable strategy might be to work toward breeding improved strains of miniature roses using 'Radtko' and similar varieties, introducing a little healthy competition to the mix (it's not exactly my taste, but I'd give it a try for a good cause). If they think Petite Knock...

Re: Petite Knock Out Rose - AVOID

I don't disagree that a mere verbal response might, by itself, change very little--although one would hope that they might consider the substance of such a response carefully.

Re: Petite Knock Out Rose - AVOID

I agree with Jonathan. I believe this is a highly dangerous precedent, and it deserves only a full-throated response. Otherwise, the nurseries won't understand how destructive their behavior is, and how much it is opposed, and then they will only too easily rationalize doing it again and again. If t...

Re: Rooted Cuttings Failure Question?

I'm really happy to hear about this runaway success--where will you find room for the new Gertrude Jekyll hedge, though? I know you have some rare varieties up there, so any improvement in your rooting percentage should help to keep those in circulation just that much longer. :-)
