I'm pretty sure my PJPII had RRD this spring. The new growth turned a weird combination of red and green and never outgrew it, plus the leaves and flowers were distorted and the canes stayed super flexible with soft thorns. Last year he grew so well and produced amazing numbers of fragrant flowers. I will try him again, but not for a few years.
Your PJPII looks normal to me, too. My PJPII had very red new growth that startled me at first, but greened up nicely, until this spring, that is.
Oh, sorry, Susan....mea culpa - all those other numbers 2495 confused my brain so I didn't notice you were another freezy zone 5 type. Obviously, everyone who can keep roses alive in those temperatures has a depth of committment I can only guess at.
I have kept new cuttings, including The New Dawn, alive over winter by siting them in their pots along the uninsulated, north foundation wall of my house and covering them with 2 L pop bottles, from which I have cut the bottom, and oak leaves. The only tricky part is removing the bottle caps when it's warm in the spring so that fungii aren't too happy.
Should work. Just aim for at least a 24" pot (the bigger the better) and an outer pot to provide some insulation from the heat is a great idea. If you can possibly site your pot such that it's in the shade most of the time (with the rest of the rose in the sun) then that will help. Also if you can run drip irrigation to the pot so that it is assured of regular water, that doesn't hurt either. Potted roses need regular fertilizer, so plan on that as well.
Your "2B" is obviously not your USDA growing zone if you are in Benicia--you might want to change that...
I guess, if I was being conscientious, I would step on the potassium more than nitrogen or phosphorous....we were always taught potassium was good for hardening woody growth for winter. Probably be more reticent with the nitrogen though.....although, it frequently depends what's left in the shed at this time of year, also.
Henry,
Could you put the link in the text, please? For some reason I see a green word "useful" followed by a green box with an upper right pointing arrow in it .....followed by the link, which won't work.
I may be able to get the paper through UT.
Hattie, so far I have only been able to see the abstract.
Ann here is the link:

Ah, Suzy, they have been right up my street. Back during my "collecting period", I grew every one available here, and enjoyed the heck out of them. But, they have to be carried on GOOD plants and many weren't. When I had virtually unlimited space, water and energy, and there were over twelve-hundred roses in that canyon in Newhall, they were all there, plus all the stripes, stippled and "haloed" types there were here in the US. Those days were great, but behind me. I no longer have the space, water and energy for that many, so my "collection" consists of those which are happier to be with me and which I want to use to create my own roses. The most "painted" one these days is Laughter Lines, which has been one of my favorites since those days. The link below takes you to the photo of it in the old Newhall garden. I hope it's as happy here as it was there. That, by the way, was an own root plant I propagated from a friend's British import. Kim

Criminey - that's enormous. I bet it wouldn't get half as big over here. Spectacular though.
Obvs, I haven't grown a fraction of what you have had....but even so, the collecting impulse is taking second place to a feeling of time not being endless and wanting to actually create a space which looks harmonious as a whole and not the insane mish-mash which results (in my gardens) from having too many fingers in too many pies.... I would definitely be happy with a few (6 or so)really great roses (white, pink, pale yellow, single, semi-double, big and floriferous) which grew in multiples.....and a dozen R.moyesii
I agree with TerryJean - I've found the Delbard painter series to be pretty winter hardy in my zone 5 yard, including Henri Matisse, Albert Sisely, Grimaldi, and of course Edgar Degas (not available AFAIK after Ashdown closed). They're actually robust and regular rebloomers for me once established, though I did lose Guy Savoy when I planted it late one year. I'm fairly sure it would do fine in a different spot and/or time when I try again. In general, Delbard and Tantau are good breeders for me in winter hardiness, not quite as good as Kordes but close.

I agree absolutely, sawfly damage. The link below is to a site belonging to a fellow in Lincolnshire, UK. If you scroll down, you will find two species of sawfly which go by the common name of "Rose Sawfly". There is a third commonly called the "Curled Sawfly" here in North America. All three species are introduced species here, originating from Europe.
I had never seen these critters in Western Canada and I was as mystified as you when first saw them on my roses in Ontario. I have all three of the common rose sawfly's in my garden.
Control: If you check your roses frequently, every couple of days, it is fairly easy to pick them off. This spring, I had a pet robin who would follow me around and clean them up as I picked them, which made this little chore more pleasant for a few weeks. If they are not controlled however, they can completely defoliate a plant or even a rose bed. Knockdown spray, pyrethrin based, is also a good spot treatment if there are too many to pick.
Cheers, Rick

I order almost every yr from them. I am running out of room, but I lost quite a few roses this past season, so am looking to either replace or get something else. Their prices are the most reasonable, and shipping is also very reasonable. I plan to order CORETTA SCOTT KING, SUGAR MOON, and FIRED UP. Still debating if I want to replace two that died on me... BARBRA STREISAND and FIREFIGHTER (HACIENDA).
Regan's is a great source also, but even for me being here in the same state, the shipping is a LOT more. I do want to order JULIO IGLESIAS, as they are the only source for a grafted one. But to make that shipping cost worthwhile, I would prefer to add a couple more roses. Just not sure what I really want yet.
(Truth be told, I shouldn't be ordering anything at all!!) LOL
Nummykitchen- I'm in quite a different climate here in 10B/24, but I was at a nursery not too far from me recently that had a row of rather stunning Over the Moons. It was a truly wonderful Apricot hue in person. I frankly don't recall the scent, but boy it sure looked good and was quite floriferous. I hope it works out for you.
And my mother has told me that my grandfather always kept a Sterling Silver from the moment it came out. It always makes me smile to see.

Home Run is actually a Tom Carruth rose.
Home Run has knockout in its bloodline though...

Mzstitch, the carts here also say the same thing and I am in central Pennsylvania so don't think the nursery is quite local to me unfortunately.
And Kim, thank you for bringing this up, I have never even thought about why a grower would mislabel a plant besides laziness so this got me thinking. Appreciate the information.
First of all, thanks to everybody for your insight...there's a lot of excellent information here already.
Some of the leaves have the necrotic spots described here and in some cases it has produced tiny holes in them. In other instances, irregular sections of the leaves have died and turn brown, particularly on the ends. At first I thought it was heat or fertilizer burn but it would only appear on a leaf here or there. I noticed the burnt-looking parts had discrete, fuzzy black undersides. Then, of course, the spots showed up. That's why I wondered if I'm dealing with both, but if they're hard to differentiate at certain phases...that's good to know.
Given what's been suggested here I guess I'll just deal with it. Some of my HTs have defoliated low down but look fine up top, and some of the leaves that are only marginally infected seem to not be getting any worse.
Ians, Michael, and Paul, thanks again. I don't know why the other photos didn't work but I'll try to fix it when I get home.

Leaf areas that are killed by fertilizer burn or whatever may be colonized by botrytis fungus, which could produce the fuzzy underside you describe. I would not be concerned about it. The pictured leaf with brown spots along the margin could have suffered fertilizer burn. That same leaf may have cercospora spots that are coalescing into a mass.
If ashy-looking centers drop out of spots leaving a purple-ringed shothole, that is anthracnose. You can have both diseases on the same plant.
I agree it is probably OK not to do anything.
It's not clear to me how they got back to exporting in one year, since grafted roses are grown for two years before harvest. Does anyone know whether there has been any change in how they are producing roses, other than not using rootstock imported from Europe?
But I'm relieved that we haven't lost another quality producer of roses.
Their wording worries me. "We EXPECT to be ABLE to ship to the States....sounds like they are not quite sure.
