Cane lesions of blackspot disease are reddish or purple.
I'm with Harry. I don't know what it is, but, unless it is canker (Hoov's link) I wouldn't worry as long as the plant seems happy. Sometimes maturing canes change color variously in springtime.


Thanks for the info. An interesting observation: I had to remove four big shrub roses with RRD last year. Three I had planted in carefully prepared holes with enriched soil and additives. One I had planted in a hastily prepared hole in mostly clay with good topsoil on the surface. The three in prepared holes had widely spread roots. The one in the unprepared hole had roots that went down to hell, but were not wide spread.

Cl Iceberg is trying to swallow my house. HMF says it is hardy to zone 4b. However, someone who grows it in a cold climate could do better at telling you how big it actually gets in zone 5. Mine in zone 9 grew up an 8 foot tall arch, over 7 feet to the house, and has gone another 6 feet up the house so far, and still going.....
Another rose which is trying to swallow my house is Sombreuil (the mystery large flowered climber). It is reputed to be a wichurana hybrid. If that is the case, it seems as if it should be more cold hardy than the zone 6 assigned to it by HMF. It is on a similar arch to Cl Iceberg, and it has made more progress up the house when it finally got there than Iceberg has. I don't have a picture of it doing that, but here is a cool picture of part of the same bush on its arch with Cl Crimson Glory and the clematis Jackmanii.

Let's try this again.
GET A SOIL TEST!
At some point in time, you are going to need to know the soil pH because it is going to bite you. The sooner you do this, the sooner you can begin to understand the consequences of what you have.
Normal pH around here can be anywhere from 5.0 to 8.0. There are plants that prefer under 6, like multiflora, rugosas, blueberries, and rhododendrons and that entire family. There are things that prefer over 6.5, like lawn grass, lavender, and most vegetables. The usual assumption is that in the northeast, soil is going to be acidic. Since both the Catskills on the west side, and the Taconics on the east side, used to be enormous limestone mountain chains, all that lime has to have gone somewhere. It is in my backyard, and it sounds like it may also be in yours.

"treatment probably depresses the amount of viral particles temporarily below the threshold level of detection of used diagnostic methods. In the course of further cultivation, the virus recovered-up and re-accumulated to a level of detection. "
Not unexpected, but depressing, nonetheless. Even if only for that particular study.
OT: it's a darned shame that the CAB database isn't accessed by more university systems.

Regarding the comment: "Even if only for that particular study."
The following link gives evidence that I have collected that I feel shows that that study is similar to what others have reported.

Ramblers have long, whippy canes, and don't rebloom. I've seen things like this done with large multiflora ramblers. I have setigera ramblers that seem capable of getting that big. They are traditionally pruned somewhat in the spring, and rather thoroughly redone after they bloom.
Now for the fun part. I am very curious what makes people think this rose is hardy? Where is the coldest place it has been successfully grown? What is the coldest temperature it has seen? In a brief web search, the coldest place I was finding was Providence, RI, on the New England Riviera.

Pictures I've seen of Peggy growing at ARE look like she MUST be bigger than 10' in Texas. When I talked with them before buying they said they had customers growing her in Idaho and Michigan and she seemed even happier in cooler zones; re-blooming when the weather cooled off in the fall which I don't think she does down south.


Just to reinforce Cecily's point that if you live in the East, blackspot disease pressure is very high, and most Austin roses (most roses period) will need regular fungicide protection if they are to keep their leaves through the growing season. For example, the company describes 'Sophy's Rose' as "very healthy," but, in my garden, it defoliates rapidly unless it is sprayed.
It is a good idea to mention your state when seeking advice. While zone 7 per se does not limit your choices, there are some roses that are susceptible to diseases on the Pacific Coast and others that are susceptible to other diseases in the East and South. Heat tolerance is also a regional issue.

I have just discovered the DA catalog is very dangerous eye candy! I hate hijacking this thread but are there any more catalogs like this one? My rose love has just begun, thanks to my unknown specimen ( to the untrained eye)I have pampered for 3 years :-)


OH THANKS SO MUCH you all! Those pictures really help! Marina, it looks like you have yours on wire attached to 1 X 1s?
Jackie, I intend to let MAC go wild with some other noisettes. The wilder the better.
I received my Sombreuil today on fortuniana and I'm going to start training her right away. I think I'm going to have to go with screws and wires in brick...
I appreciate all the information and photos. Very helpful!

The polyantha White Pet (aka Little White Pet) might be a good possibility. I got mine from Vintage Gardens but don't know if it's still available. Other on-line nurseries might have it. It's widely regarded as a wonderful and healthy rose that blooms prolifically.

No Lyn, if you were building raised beds and needed soil to fill them, purchasing sandy loam and mixing it with your glacier slurry to make it hold water better may work. But, for simply improving what's in the ground already, continuing to mulch heavily with whatever organic material you have readily at hand will likely serve you better and far more cost effectively, not to mention being a WHALE of a lot easier dragging up your hill!

Mike,
I own one fragrant cloud. I bought it last year. It survived this winter with no die back and minimal winter protection. Granted, we had a mild winter. I think with winter protection, it would survive any winters here.
From what I can tell, the fragrant cloud loves the heat. We had a very unseasonably hot summer. It was putting on blooms when all my other roses were on strike from 100+ degree temperatures.
When the blooms open, they look like 5 inch popcorn balls. I'm very attached to my fragrant cloud. c:

After having one in the shade (that survived fine) for 3 years, I bought my second this year. Both are on Dr. Huey and very strong and mostly disease free. She thrives in heat. Mine cuts beautifully and that fragrance! When I bring bouquets in to work, Fragrant Cloud, Chrysler Imperial and Double Delight get the most ooos and ahhhhs.

If you have decent drainage, go ahead and get them in the ground. Set the bud union at ground level. Plan to winter protect these next winter. Once these (fortuniana budded) roses have a good root system and get through their first winter, they'll be fine. You should see some really nice blooms this coming fall. I have 30+ roses on fortuniana rootstock. 10 came with me from S.E.FL when I moved to N.GA and have been in the ground since I moved up here in 2008. All the other 20+ bush's have come from K&M. Don't be afraid of fortuniana grown roses. Just be careful the 1st year.






I can't help say who it might be, but looking at it the canes seem smooth. A plus on such a beautiful climber.
