I am happy to report that I seem to have panicked too soon. I just spoke with a gentleman at Chamblee's who assured me that I could order retail mail order from the complete list, including the oldies and goodies like 'Aloha', 'Marie Daly' and the rest.

I do like the Chamblee's roses because they grow and thrive even in my zone 5 climate.

I am searching for Sea Foam Standard Roses for purchase. I can not seem to find any grower who has them. Any help?

I've been reading up on old garden roses lately, as some varieties offer advantages for my climate, and have found some interesting comments by experienced growers.

The first comment is Reply#1 in Discussion id 71-434, on this page:

I can't post the link to the second comment in this post, due to a glitch in the forum software, but it's in the comments on 'Paul Neyron' and is Reply#1 in Discussion id 52-806.

What I am curious about is the role of pH with regard to health of different classes of roses. In the local sub-tropical climate, planted in local clay-based volcanic soil with a pH around 6, Teas and Chinas seem to do very well and have good disease resistance. Other classes of old roses seem to do less well, as far as I can gather from the limited information I have at the moment.

The grower in the first discussion seems to be unable to grow classes which are known to do well in hot weather and acidic soils (and incidentally have a predominantly Asian background) yet appears to have good results with other classes that obviously like alkaline soil and water in her climate (and incidentally have a predominantly European background).

The grower in the second discussion was apparently able to change a sickly HP into a thriving one, just by altering the pH of its micro-environment, and despite being in a climate that predisposed the rose to fungal infection.

My questions are:

1/ Is it established that Chinas and teas prefer slightly acidic conditions, while other classes of OGR's prefer alkaline? And

2/ to what extent, if any, is management of pH known to be tied to disease resistance of various classes, in particular resistance to black spot under hot and humid conditions?

interesting questions :)

in principle one might answer yes to your 1st question, remembering of course that some rootstocks also have pH preferences, and that should not be forgotten ...

I believe a neutral+ pH can be beneficial in ameliorating blackspot as well as other challenges to roses. a method to consider, without altering soil pH, is a regular foliar application of Seasol (very high pH).

Good point about root stock. I should swot up on that.

Seasol is great stuff and I do slosh it around every so often. The only thing wrong with it is that the fragrance of fermented seaweed doesn't exactly add a more salubrious note to the fragrance of 'Mister Lincoln', or anything else for that matter, so one has to be careful where the Seasol goes when a bush is in flower.

The other thing I've just done, after seeing these hints about alkalinity, is to throw some leftover wood ash around the base of the roses. I've had it sitting around since winter and had almost forgotten about it, so this seemed like a good use for some.

Oh and just to confuse things further, apparently the famous 'Kazanlik', which is not at all closely related to Teas and Chinas, will not only grow happily on slightly acidic soils but will also grow and flower in a sub-tropical climate.

The 2001 reference for it mentions the soil pH used for commercial growing in New Zealand:

"The damask rose enjoys heat, water, and high fertility, and under these conditions it flowers well. Roses can be successfully grown on a wide range of soils but they do best on well-drained soils, with a soil pH of 6.0-6-5."

And there are several photos on this site of it growing and flowering in Manassas, Virginia. Example:

As a passing thought: Thomas for Roses buds onto multiflora, which should do well in your soil. Roses budded onto Dr Huey, as used by most other old-rose nurseries in SA, prefer alkaline soil.

Thanks. That's worth knowing. It's also interesting because Montville Garden, just up the coast from me and with similar conditions, has had a lot of trouble with grafted roses dying on them. Most of their successes have been with own root roses, mostly Teas and Chinas, although they do have a thriving Zéphirine Drouhin and a few other odd ones.

Anyway, perhaps the grafted roses they were getting were on Dr Huey stock. If I make it to their next open day (I think it's around Easter) I may ask them about the source of the grafted ones.

This may also be useful information if my baby 'Peace' doesn't do well long term. I could source a replacement from T4R with a multiflora rootstock.

If you are talking about "The Shambles" at Montville, ask them about a foundling tea rose they were calling “Talgai Courtyard Rose No. 1”. I don't know if they ever solved that one.
Reply #7 of 9 posted 28 JAN 15 by Give me caffeine
Yes, it's the same place. For some reason their website is called I'll try to remember to ask about that one.
Reply #9 of 9 posted 25 APR 15 by Give me caffeine
I was up there today for the open garden, and asked Michael about the Talgai rose. The verdict was that he still doesn't know what it is. He said he could speculate, but it would be pure speculation.

After thinking about it a bit, I've come up with a way to improve the fragrance of Seasol while also increasing its anti-fungal properties: clove oil.

I had some clove oil sitting around anyway, and it's known to be a good fungicide. Since some roses have clove notes in their scent, it's fairly obvious that roses (or some of them) already have genes for making eugenol, so a dilute solution of it is unlikely to do any harm to foliage or flowers.

So, what I did was mix up a litre of Seasol for foliar application, then throw in half a dozen drops of clove oil and a drop or two of detergent (just to help emulsify the clove oil). The result is Seasol that smells like cloves, which a marked improvement, and which should do an even better job of knackering those nasty fungi.

I'm going to test it and see how it goes. We're getting full-on sub-tropical summer downpours and humidity at the moment, so it's an ideal time to test.

Hi, I'm looking for a purple climbing rose that has almost an English Rose type bud (very frilly, not like a tea rose more like a cecile brunner). Do you have any thoughts

You might try Tess of the D'Urbervilles as a climber! Defenitely an Austin (English Rose).

thanks so much, appreciate the quick response

It performs well at my place, but I had to relocate it, for it grew too high as a shrub.

Yes, Pam knows many of the "old roses".
