Re: Can any give suggestions on these roses for breeding?

"The majority of roses I chose either based on suggestions to use as parents, because I like the color/traits, or because they seemed to be used successfully for crosses in Help Me Find" That was once my thinking as well, but I would suggest that what that means is you are ultimately selecting for r...

Re: I'm new here, so I'd like to say hi!

Hi, Josh. Welcome! I don't know that you should worry about not being "ready" to be involved in "serious conversation". I consider myself exceptionally green at this, and that never hindered my chiming in. ;-) Having said that, DO take comments from me with a grain of salt! From my limited experienc...

Re: Why some crosses fail

Thanks Karl! I think that when I find time to peruse all the articles, this will address a number of questions I was trying to ask (but probably did poorly) in a prior thread.

Re: Show and Tell?

Thanks for the response. I personally have had nothing worth photographing this year, IMO, though I have had a couple seemingly exhibiting admirable health, and giving me the impression that *were* I to relocate to a better site, they might be rather floriferous. It's just that the blooms thus far l...

Show and Tell?

I don't have anything of much interest to show for this season, and so I'd like to revert to vicarious enjoyment of other's successes in one thread. I'm assuming it's late enough in the season that folks have had opportunity to enjoy the fruits of previous year's hybridizing labors. Caveats as to no...

Re: Grid for pollen measurement

Cool! Slightly OT, but I'm curious as to what kind of magnification would be required to view root-squashes to determine ploidy? I'm assuming that's requires a heckuva lot more magnification?

Re: in the rose family

Those are impressive, Stephen. Have you thought about how many acres worth, and how many bushels ultimately, those are good for? That should make you feel better about your pace, I would imagine.

Re: rugosa x glauca seedling

Rob and Tom, you guys give me too much credit! I really don't know what I'm talking about. (I've never used any of those species -- it's all purely speculation.) Standard disclaimer on my part there. I am very good about opining about things about which I know very little. ;-) Not that I want to dis...

Re: Variegated roses?

Dumb question, but if it's a seedling from parents that don't present similar signs of "virus" and if the seedling has never been grafted, isn't the probability of such ridiculously slim? *If* it were a virus, is it conceivable that the carrier for the virus would *not* have exhibited such extreme v...

Re: Helpful tip plant markers

"the old string and paper rolled wax pencil" sounds like what I call a china marker. I thought it would be a great solution too, but found that the pigment in the ones I bought faded pretty quickly in the sunlight at our latitude, much to my surprise. Perhaps you have found a better brand? *When* an...

Re: Rosa kweichowensis

Yes. I couldn't really tell, but the carpels on that first photo also looked to be the type to form drupelets, hence my comment on fruit. Presumably, however, there *is* such a rose, erroneous photo notwithstanding, no?

Re: rugosa x glauca seedling

I wonder if R. fedtshenkoana derivatives could reinforce the foliar color, or if R. foliolosa derivatives might serve to reinforce flower color? Dunno if R. f. could, in and of itself, bring back some rebloom. I have not worked with any of those species yet, though they have long been on my wish-list.

Interesting. Looking at the photo, I might have presumed something in the Rubus genus, without closer inspection or any visible fruit. (Move over, rubifolia!)

Re: Putting honey on stigmas before pollination??

I had wondered about using a sugar water solution on hesitant roses when the stigmas of such don't generally look "sticky" and ready to accept pollen at any stage during normal development. I thought about trying such on speculation that some reluctant mothers might just fail to trigger tube germina...

Re: When hardiness isn't an issue...

LOL! I didn't actually expect you to take me up on it, Kim! I would love to trial it, but unfortunately the only realty I have that is amenable to growing roses is in the front yard of my small lot, which is not secure. I'm sure that I'm a little neurotic about such, but I tend to think of TX as ros...

Ah... You live in one of *those* climates. (Okay... I'm not jealous...)
Still a beautiful rose, but I would imagine more pink, if not a frying dark pink, in something like my climate. Mind you, if you want me to give it a whirl for you to confirm... ;-)

Re: When hardiness isn't an issue...

So I did see those colors correctly. The burning to a color other than a shade of red is what surprised me looking at the photos. I wonder if the hues change with the temperatures? I could imagine from the overtones I'm perceiving, it might be more mauve in cooler weather. (I have no idea why I'm pr...

Re: Seedling

I wouldn't sweat the size of the boom, Joe. In fact, I would be surprised if it *could* be made much larger. Others with more knowledge will hopefully set my assumptions straight, but I don't know of any e.g. fimbriated rose blossoms that achieve the otherwise expected size. Serratipetala and Groote...
