Re: Ploid Cross Matix Tool?

Stefan, Txs for the feedback. I am slowly coming to the conclusion that the knowing ploid question is not a rigid straight jacket conformity rule in hybridizing. This is useful as in my searches it seems a challenge to find the ploid data for a good chunk of my rose inventory, and also not yet recog...

Ploid Cross Matix Tool?

I read this ploid focused abstract with interest, and as a layperson. I conclude for my purposes one can cross pretty much any ploids in a plan up to tetra with a margin of success. Without saying anything of the garden merit of the seedlings. Or does anyone know of a published reference - rather th...

Re: Rooted Cuttings Failure Question?

Hi Stefan My large RDxS is in the bay window plot (south facing) and is sheltered from north west and east winds plus gets whatever radiant is thrown from the house wall say 2-3 feet away. Started as a rooted cutting given by friend plus l added another one l rooted 6 inches away - thought it was on...

Re: Rooted Cuttings Failure Question?

Txs Kim and Stefan, Gertie is likely to join the last 2 surviving Gertie’s in the sheltered bay window. A confined but magnificently performing RDxS in bay spot will be transplanted in spring to replace a spino hybrid (Aicha s.p.?) that grows to a giant by fall but has poor winter hardiness - most c...

Re: Rooted Cuttings Failure Question?

Sign-off time on this thread on a high note ... 3 out 3 for successes by following the advice in thread. And topping it off with number 3 the illusive Gertie has for the first time after many tries over the years (decade plus), made it to producing new growth from a cutting ... bit melodramatic, but...

Hi Stefan That’s another good suggestion - don’t recall planting one in that spot ... but that means pretty well nothing as recycle growing spots quite often and old forgotten roses presumed departed will pop up. .

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

Hi Margit, Good potential lead to chase, leaves more like "Na". Got to agree about the head scratching lack of any strong spino influence on the leaves (and still hardy so far). A little stronger on the canes but not overwhelming. I am use to "fern - like" spino leaves, and extremely thorny (bristly...

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

Thanks David for suggestions to pursue, I agree it sure looks like spino (but off in minor ways). My Kakawa is about 10 feet away, and a Butterball (produces a copious quantity of hips), Hunter (ditto hips), Therese and Alba Semi-Plena surround it. I exclude Chinook Sunrise as it is too new. Must co...

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

Contacted best potential commercial source of rose. It is not one of theirs.

Open season now for pursuing claiming the study rose as "OP germination - moi garden origins" until shot down by "Horbilis. facts". Will dig down in spring to see if grafted.

Re: Rosa beggeriana nigrescens

Also note R. Beggeriana also likes slightly alkaline soil - have tonnes of that, but been working on making it more of an ericaceous soil. May back pedal where they’re going to be planted.

Re: Rosa beggeriana nigrescens

Hi Stefan, yes there is a non-Loubert bloom photo, but likely has commercial protection. It looks the same color, maybe ever so slightly darker, but we know the variation different conditions cause. The unopened bud form is similar to Polstjärnan to my eyes - but a lot of my other CDN heritage roses...

Rosa beggeriana nigrescens

I have an opportunity to acquire this rose. I am speculating - does not feel like much of leap - this rose is related to R beggeriana parent of Polstjärnan. It has color that is appealing - l call it a red single - for using as another candidate for getting the bone hardy non- white red rambler. HMF...
