Re: AC de Montarville

Dammit, Rob, why do you keep getting interesting roses that I should probably have? I feel like I'm trying to keep up with the Byrnes's here.

Re: Hardy, Everblooming Climbers

I have Ross Rambler and Ross Rambler #4. Both get some pretty funky spots later in the summer, but are insanely hardy. Both set hips, but are hard to pollinate. I think it's RR4 that impresses me as a potential tree rose for cold climates. It hasn't suckered that much and is tip hardy 8 or 10 feet i...

Re: Hardy, Everblooming Climbers

I grew Radler's Highwire Flyer for the first time last summer. I was impressed with the large, bright colored blooms. As a Radler rose (and a pink one) it should be very healthy. It is marketed as a Zone 5 climber, which means it would have upper cane hardiness in Zone 5 and therefore might have exc...

Re: Hardy, Everblooming Climbers

Thank you, Larry, for your analysis. I think my R. xanthina had trouble shutting down as you mention in your last paragraph. They seem to stay lush green until freeze-up. We had a blessedly long and slow fall a couple of years ago, so I thought they'd had a chance to harden up. But then that spring ...

Re: Wild Edric

Thanks, Roselynn, for the suggestion of Snow Pavement. I have a number of interesting seedlings of Henry Hudson growing, but no longer have Henry Hudson itself to play around with. It didn't seem to set hips super easily, and I haven't seemed to be able to get one lately (haven't tried too hard). I ...

Re: most anticipated cross?

Rob, I wouldn't give up on Commander so quickly. I really like it and it gives a dose of vigor and perhaps health. The reblooming seedlings that it does give can be heavily reblooming. You can screen out the non-bloomers at a fairly young age to save space. Just understand that you should cross it o...

Re: most anticipated cross?

Oh, yeah, unfortunately I grubbed out the R. carolina x RDxS because they got some disease problems. One of them I sent to someone down south, so maybe it still exists. They were clearly hybrids. So no chance to try again for rebloom.

Re: most anticipated cross?

Philip, I'm thinking the odds are way worse than that. First off, back when I was crossing with RDxS I don't remember getting any rebloomers even when crossing with rebloomers. I imagine it could give a small percentage in the first gen when crossed with a rebloomer. (It would be fun to check that o...

Re: most anticipated cross?

Just to blab about a little guy popping up: 1206 x 1113 1113 I talked about and pictured above. 1206 is such an anomaly that I wonder if it was a seed that jumped ship, although it doesn't really match any other cross either. It's heritage is: [R. carolina x (Red Dawn x Suzanne)] x Commander Gillett...

Re: First germination of the winter

Rob,

Smoothie x Ann Endt. Interesting. Here's hoping for a fragrant hardy thornless bright purple everblooming rose about 2 feet tall!

Oso Easy Pleasy.

What the heck? David's got another rose coming out? I can't keep up! It looks nice, like maybe a hardier alternative to Little Mischief.

Re: First germination of the winter

Whoa, 5% bleach, well, I guess I don't really know but intuitively it seems like that would kill them.

Let the soil get slightly dry between waterings. As dry as possible without risk of the plants wilting.

Off-topic, but I thought this well-written article on potato breeding might be interesting to some:

Re: Pollen from Rosa xanthina spontanea

I grew some of the R. xanthina from the seed that Kim mentioned. Note that they were essentially not able to bloom in my USDA Zone 3b climate because of winter dieback, so I grubbed them out.

Re: Experience with Hansa?

Duane, It's really odd to consider how Hansa is a prolific seed-setter for some and has no hips at all for others. What are the factors? Our climates shouldn't be vastly different. I think there was someone on this forum from Finland or the like who mentioned several years ago that Hansa set hips. A...

Re: Experience with Hansa?

I've never spotted a hip on my Hansa. I kinda wish I could use it - hardiness, rebloom, and the peonin thing seem like valuable traits. One idea is to have a potted one and try higher temps in a greenhouse. David Z's reported that high temps can overcome self-sterility in polyantha roses; maybe it w...

Re: most anticipated cross?

Hi Philip. I'm thinking the R. annaciculendtaris (hey, if Kordes gets a new species name then so do I) is about three or four years old. I don't think I've posted pics and not sure if I have pics. It was a nice purpley color but the blossoms are very short lived if I remember correctly. I'm assuming...

Re: most anticipated cross?

Sounds fun, Duane! My seeds are stratifying in bags right now, and I'm just starting the process of sowing them into flats, which will be returned to a cold environment until later in the spring. I'm most optimistic about crosses that involve a rose of mine of lost parentage that I call 1113. See at...
