Re: Any merits to R. woodsii ultramontana?

Right? I don't grow Fedtschenkoana to have any idea what kind of ungainly architecture it might yield ...and then there comes the issue of hanging an interesting flower on that... I've been wanting to obtain glauca, soulieana, and a few others so that I could play with foliar combos and try to get a...

What about laevigata?

Same question as my woodsii ultramontana post...
I assume that one big deterrent to its use is the lack of cold hardiness in this species, but does anyone have experiences with it, or know of good (garden worthy) descendants ever coming out of it?

Re: Any merits to R. woodsii ultramontana?

"I'll have to hope nature will be so kind to help me" Nature is not kind. This I learn as I get older, wiser, and more decrepit... ;-) "Kimberly" actually resembles the roses in Santa Fe from which I collected hips. I wonder how she would pair with a R. fedtschenkoana derivative. Probably would suck...

Re: Any merits to R. woodsii ultramontana?

"It's ironic Rosa woodsii is the most geographically widespread Rosa species in North America, but it hasn't contributed much to the development of roses in Canada and the U.S." Yeah... That's precisely the reason I was asking, Paul. It seems to have *some* merits, and yet... Surely folks *have* pla...

Re: Any merits to R. woodsii ultramontana?

My Santa Fe (R. arizonica? R. fendlerii?) roses were actually pretty attractive, having almost willowy bluish colored foliage, bronze stems, and bright red heps. It bears little resemblance to the things in CO, though they endured *very* different weather. I'm hoping the seedlings won't hate central...

Re: early culling of species seedlings...

Wow, Joe. I like your artist's/breeder's mission statement. You should have saved that for the newsletter! ;-) Vigor is one that everyone always touts, but like Karl, I've wondered if that doesn't eliminate the selecting for compact plants. Clearly breeders like David Austin select for vigor, and I ...

Re: patent law confusion

Just a quick thank you, which I realized I neglected to post, to all, for the clarifications! No wonder I was a little confused. I wasn't sure what constituted disclosure, as in my example, for instance, Carefree Sunshine is acknowledged as having been bred prior to 1991.

early culling of species seedlings...

Knowing that they won't bloom for a while, but having entirely too many... Do folks have any rules of thumb for culling species seedlings? I read of (I think it was a double "azalea" flowered snapdragon) some seed for which growers were advised to discard first germinations as they would not be of t...

Re: R. davidii

Wow! THat's a scary vigorous seedling. I gather the vigor came in part from Altissimo? As I say, I know that both Pretty Lady and Baby Love were touted as being highly disease-resistant, and I noted R. davidii in the pedigree of both. I wondered if it was a primary contributor, or just coincidentall...

The two would have reacted to create peroxyacetic acid (PAA) in excess H202 at that concentration.

Re: Any merits to R. woodsii ultramontana?

Peroxyacetic acid, btw, is an antimicrobial, hence the idea to use a little cider vinegar in addition to the peroxide. I figure acetic acid is probably in rotting fruit in the same family, and thus might also serve as a trigger for germination, though I have *nothing* to back that thinking up... I d...

Re: Any merits to R. woodsii ultramontana?

Poorly, to be honest. I think they probably spent *most* of that time as entire dry heps in the fridge. This winter, I soaked the heps in a very dilute solution containing roughly 5 parts H2O2 to one part cider vinegar (by which I mean, "parts" directly out of bottle, being I guess 3% and 5% solutio...

Yes, thanks David and Warren. I have seen several attractive seedlings from Warren having davidii in them, and from the photos, they do look very nice. I should have been clearer in expressing an interest in the *specifics* of other's experiences, which is to say, whether folks feel that the species...

Re: Any merits to R. woodsii ultramontana?

The seed I collected in Colorado came from rather scrappy, and at the time, somewhat unattractive little plants, but clearly they were survivors, and on their way to dormancy. (I think it was early October, and they had already had some freezes.) The ones from Santa Fe area, on the other hand, made ...

Any merits to R. woodsii ultramontana?

When I travel, and find species roses with hips I frequently collect some. I have heps from a trip near the Rocky Mountain Nat'l Park in CO that I presume to be woodsii. A scrappy little plant I found around a mountain lake, and topping out at around 18". No blooms, obviously, just ripe hips. I also...

Re: R. davidii

This is one that has intrigued me, though I haven't been able to justify the realty to plant very many species in my little yard. R. davidii figures into pedigrees of some rather healthy plants, including Baby Love and Pretty Lady. (Baby Love, admittedly, has fallen off its pedestal somewhat in rece...

patent law confusion

Apologies for a dumb question... I am a little confused (forgetful) about patent regulations... Does patent countdown begin when rose is bred, introduced, or patented? As a for-instance, I note that Carefree Sunshine was bred before 1991, introduced in 2001, and patented in October of 2002 (with the...

Re: Grow light recommendations

The rate of development of LED's has been astronomical, and I would argue that a paper written in 2014 is no longer germane. A $60 module requiring a $60 HLV dimmer five years ago, for instance, is today obsolete when compared to a comparable $7 module working with a standard dimmer. (My city does s...
