Re: Calcium Nitrate protocol, again...

I don't know if anybody is shopping for NO3, but at Walmart, I saw that Alaska naturals (the folks who sell the fish emulsion) has a new line that includes a Calcium Nitrogen Magnesium solution, of calcium nitrate and magnesium nitrate (N 3.00%, Ca 3.00%, Mg 1.00%) in a quart for less than $10.

Re: Rosa maximowicziana seeds

Well I was just thinking if it were, then seedlings of R.m. might make decent pairings with your setigera serena offspring, David, while perhaps avoiding the potential weaknesses of e.g. polyantha mates. Of course hypothesizing is always a lot easier than realizing the intended result.

Re: The aim is also to produce fertile offspring

Those pendulous trusses of hips are quite showy in their own right. Don't know if it's the lighting/photography, but the color on the fruit of the Sympathie x virginiana hybrids is quite flashy too.

Re: Rosa maximowicziana seeds

Just came across this thread, David, and was curious as to whether you had information pertaining to this species resistance/susceptibility to RRD. Is it better than multiflora?

Re: The Complete Chloroplast Genome of a Key Ancestor of Mod

I have to confess that I am not at all familiar with the species R. lichiangensis, and have no idea as to how it might tie into the genotype of modern roses. I am, however, a little intrigued to think that china roses might have some linkage to the Synstylae. David Zlesak had observed that in workin...

Very interesting article. Thank you, Warren. (Admittedly, at the third sentence I feared I was not going to be able to follow along!) Once the new species were created, I presume they evolved somewhat over their range

Re: 2017 Virginiana Hybrids

A bit off topic, but I'm thinking I need to expand my species base, and was looking at either R. carolina or R. virginiana, and wondering about the relative merits of one over the other. If I'm not mistaken, Warren, you have worked with both, no? I've been seeing more work being done with virginiana...

Re: R. multibracteata

I was rather hoping that multibracteata might breed like a tetraploid rugosa, to which it is somewhat related, being in the sub-section cinnomomeae. I, however, have zero familiarity with this species. I don't recall the hybrid purportedly having an unnamed descendant of multibracteata in its lineag...

R. multibracteata

Has anybody worked with this species? I found it in the distant pedigree of a few intriguing cultivars, and I'm wondering what the species offers to progeny. It's tetraploid to boot. I like the look of the species itself.

Re: Not scientific, but interesting

Thanks, Don. I actually need to walk back some of my assertions. Apparently, Kordes didn't start the no-spray regimen until the 90's. I had thought it was earlier. Radler bred K.O. in 1988, so he was way ahead of the curve, and deserves the credit. Kordes roses had a reputation for good health befor...

Re: Not scientific, but interesting

BTW, Dolomiti should have similar "Exceptional" rating on US system, were it available stateside, and assuming the "exceptional" isn't a typo from a copy writer who meant to say "excellent". I don't know that Star will focus that much attention on expanding the Kordes representation though.

Re: Not scientific, but interesting

It bothers me that they threw out the BS vs Mildew distinction. Mildew isn't a problem here. But Fire Opal/Roseromantic is one of the few roses on Kordes' own site that gets not only a 4-star for BS, but also a 4-star for mildew. It's not a new rating system. Just a lamer one. Kordes is very self-cr...

I have heard good things about Poseidon, though I've never grown it. Plum Perfect is marketed as a heat tolerant mauve. Both are Kordes roses.

Re: Funny to see roots coming out of nodes of these cuttings

I'm hoping to get the chance to cross its offspring with some of my stronger Kordes roses, so that might give more strength to the stems. We'll see if the wichuriana in Kordes hurts.

Have you tried any of the other more esoteric synstylae? Something from the Brunonianae for instance?

Re: reds from KO/Home Run, etc...

The two trees in our backyard pretty much shade the entirety of it. They are probably about 60 year old live oaks, so aren't even fully deciduous, but I was thinking that rampant climbers *might* be adapted to that sort of thing. You are a good enabler, sir.
