Re: Some current pictures...

Cool stuff, Tom1 Speaking only from 2nd hand anecdotal experiences, I would suspect late blooming Asian Synstylae as the parent for that first one, though as I mentioned in another thread, I do have some setigera x mutabilis seedlings. Does Lemon Splash have a propensity to BS for you? I would imagi...

First blooms vs mature blooms on seedlings

I was just wondering if there was a thread already in which folks have posted "before and after" photos to show the potential that seedling with a "meh" first bloom might ultimately present. Over the years I've seen some first blooms that blow me away for their substance and form, and it kinda makes...

Re: Andrew Barocco - Texas hybridizer

Cool. That looks like quite an operation. I wonder if he would be willing to do a tour/interview for someone to write up on for the newsletter. With a child and busy work schedules, I'm dubious, but since ARE is a 2 hour drive from us, I would love to see if I could make the time to do such, if he c...

Re: Bellecom x OP

Thank you, Joe, for pointing that discrepancy out to me. I was taking it on faith that the rose out there was diploid... Knowing that Legacy allegedly came from "the probable amphidiploid", I've always assumed the rose that is in commerce as "legacy" -- being the same rose as Comm. Gill., and presum...

Re: Open pollinated seedlings from F1 carolina X gallica

A little off topic, but I strongly suspect that Ralph's R. soulieana was not the species. He got a number of repeaters from the plant, and the foliage and stems lack the grey bloom of the species. Nonetheless, there are a good many purported species offspring out there that repeat when they shouldn't.

Re: Is sterility sometimes a physical problem, and not genetic?

Interesting. I never thought to worry about going the other direction -- I always presumed that pollen would have a "shelf-life" of a few days, and if it was sticking the flowers, it would in good time be induced to germinate a pollen tube. But I suppose the pollen wouldn't really even "stick" to ta...

Re: first roses of the year

Marty, I think Brian was wanting to know if the two-tone was a sunlight induced color change, or if that's a stable trait that would also occur in e.g. a greenhouse setting. The confusing terminology is one I am guilty of. I saw someone refer to sunlight-induced color-changing as phototropism, and I...

Very pretty, Marty. I think the foliage will set off those blooms beautifully. Is that the first bloom of the seedling? I'll be curious to see how it develops on a mature plant! A mini Abigaile could be quite beautiful. I never managed to get *any*thing from Gigi. Congratulations. And *my* first blo...

Is sterility sometimes a physical problem, and not genetic?

I've become accustomed to thinking that some plants are just incompatible as parents for genetic reasons, but I recall once hybridizing with Orange Triumph, which was a very reluctant mother. I was just starting with hybridizing at the time, and it didn't occur to me to blame the plant. And so I rat...

Re: great foliage

That is some gorgeous foliage, and a very impressive pedigree. (Ah, yes... But how does it look come September? ;-) ) I think that's a cross worth repeating a few times -- there is a LOT of potential in the genotype, IMO. Is she as floriferous as the pedigree suggests she might be?

Re: Looking for Some Varieties

I can't help with those, but if you are flexible enough to substitute, and if in 777 you're primarily looking to find a well reviewed red, fragrant nearly thornless HT, I personally have been wondering about Orard's Firefighter. It doesn't have the mauve inclination, however, if that's of value to y...

Re: Flowering, Drought and Disease Tolerance, and Landscape Performance of Landscape Roses Grown under Low-input Conditi

THanks, Henry. Very interesting. It's good to see some of the not-so-common cultivars in these parts tested, but I'm a little surprised by the lack of some which I would have thought to be the truly tried and true, by Texas standards. Katy Road Pink, the listed parent of Katy Girl, is in fact a stud...

Doug, I missed your post earlier, and I'm only just wrapping my head around it... That is, in theory, a hexaploid (huh??!!) (gallica (56n) x cannina (35n)), with a darned-if-we-knowploid (14, 28, 42, or 56n) acicularis? How do Alba Maxima and its sport, Alba Semi-plena, usually segregate when used f...

Re: Unreduced pollen in roses

A little off-topic, David, but in the case of unreduced pollen from a diploid creating a polyploid, are those polyploids likely to have any more cold-hardiness than their diploid seedlings? I recall reading that polyploid species are more common in colder climates, but don't recall the supposed reas...

Re: Varying Germination with Differing Pollen Parents

Mike, my setigera serena x mutabilis was a germination from last year, and it is still too small for material. I don't know that it will have pollen to offer when the time comes -- my impression is that the likelihood favors a dioecious female. I expect another 2 years before it blooms regardless. I...
