Re: Prairie Joy x Cherry Frost

I just had the thought that if you popped 1027 into Zone 5 or warmer it might be a stunning climber or very large arching bush.

Re: Prairie Joy x Cherry Frost

Good to see 1027 in someone else's yard, Rob! Mine hasn't been as smothered with blooms in the past few years for some reason as it was before when I took cuttings. And somewhat hesitant to repeat. And difficult to breed with....not a good seed setter and as a pollen parent the results have been uni...

Re: So what's your magic number for days to harvest?

I think the whole concept of seeds is amazing. How there can be a little life that survives inside a dried-up brown pebble for years and can spring to life even after that.

Re: So what's your magic number for days to harvest?

Wow, that's cool, Chuck. Congratulations. I was just thinking about this topic because today I harvested seed from the polyantha Pretty Polly Pink on potted plants that I had brought inside because the hips were totally green when winter came and I had to shut down the greenhouse. The pollinations w...

Re: How common are sports?

Just keep an eye out. A flower-color sport will be pretty easy to spot. I had William Baffin sport to a soft pink. Also Morden Blush sports to white quite often. Other than that I haven't seen any. So no, it's not worth putting effort into just looking for sports, but if you look at your roses once ...

Re: rose hips without inner hair?

Hi Srdjan! There has been discussion on this forum in the past about breeding for ediblility. Maybe you can find the discussions if you search. (try using google instead with a search term that includes "site:rosebreeders.org"). I seem to remember someone mentioning Old Blush, maybe due to lack of h...

Re: How important is own root

I think you're making a good point. Roots are an important characteristic of a rose. Seedlings should be selected for good root characteristics as well, whatever they are...just select for roses that grow well in various conditions and you'll automatically be selecting for good roots. Own-root is th...

Re: New member

Bonjour, and welcome to the forum!

I wonder how Pierre is doing? He's from France and has done a lot of breeding, but hasn't posted for a while. His username is "pierre" so you can maybe send him a message here.

I've been to France many years ago and would love to visit again some time.

Re: Anyone breeding for fall color?

Duane, There are very big differences between using R. glauca as a seed parent vs. pollen parent. The asymmetric meiosis makes it contribute one set of chromosomes as a pollen parent and three as a seed parent. Therefore seedlings from R. glauca as a seed parent will bear its characteristics much mo...

Re: Variegated roses?

Sorry to disappoint...mine was planted in the field and grew somewhat but didn't do much. I expect the variegation to be gone in the spring. Check back next July!

Re: Odd little seedling

I believe I labeled this little guy to be dug, with the intention of sending it to Kim for growth and propagation, as he mentioned above.

So it is probably in a pile of roses somewhere in my bare root building. Kim, would it be best to send it now or should I wait until March or April?

Re: All A'Twitter x Yatkan

Good point, Plaz.

I'm trying some outdoor seed plots this year to plant larger quantities of OP seed from the aforementioned modern-species F1's, planning to scout for those 27 out of 1000.

Re: All A'Twitter x Yatkan

It is likely that your R. woodsii seed could benefit from a warm stratification period prior to the cold stratification. If you're in zone 5 that should make your work easier, because the once-blooming seedlings in the first generation of a species-modern cross should be able to have enough live woo...

Re: All A'Twitter x Yatkan

Duane, I first must give the caveat that my R. virginiana and R. carolina came from Lawyer Nurseries, and look very similar to each other. My assumption is that all they're either one or the other, but I haven't gone to work to figure out which one it is. Therefore, when I talk about R. carolina or ...

Could you expound on why that was your choice, as I've read a lot about sterility issues, and apparently that isn't the case with the pollen you used. Any thoughts?

more carolina descendants

Blue for You x (R. carolina x (Red Dawn x Suzanne))

Strong fragrance, good vigor. Non-remontant. I used its pollen quite a bit to see if I could recover rebloom.

I have another seedling with similar blossoms which is Blue for You x (R. carolina x R. centifolia).

I'll turn this into a show and tell thread because Duane asked a leading question... 1128: 1048 x FIVI3. I liked the very double, pale yellow blossoms and shrubby habit of this rose. Seems healthy, vigorous, and hardy and has fun genetics. Non-remontant. 1048 is YWP (https://www.helpmefind.com/rose/...

Hi Duane! Thanks for asking about my babies. I love to blab. The pollen was successful in creating hips on Miracle on the Hudson, and Oso Easy Italian Ice, I believe. I've collected the hips, but haven't cracked them open yet to count the seeds or entered them in the computer. The one hip survived t...

Re: genetic incompatability? What do you think?

Kind of on this topic...I had a row of either Rugosa #3 or Ann Endt (can't remember offhand) X R. carolina. About six plants. To varying degrees they showed the narrow, somewhat odd leaflets that resembled the effects of herbicide exposure. They were able to grow up and bloom. One of them had no ant...
