Really love HP's, and portlands

I really love some of the roses in this class and was wondering before I spent hundreds of dollars on the bands , would I be able to grow them in my climate? they include
rose de rescht
souvenir du dr. jamain
leda
rose du roi of commernce
yolande d'aragon
gros choux d'hollande
reine des violettes
and autumn damask. I know they are not all HP's and portlands, but this is most of the ones I really wanted, I'm not the most experienced rose gardner, nor an I a newbie, if anyone living near my area could please share their knowledge I would greatly appreciate it :)

RE: Really love HP's, and portlands

Alana: I was hoping a Southern gardener who has more knowledge than I do about Portlands/HPs/ Damasks would respond to your question. Gardening in coastal NC, it's been my (limited) experience that members of those interrelated classes tend to struggle in the heat of our prolonged summer season. Symptomatic of their southern discomfort are foliage "issues" that gardeners in milder climates apparently never experience.

Should you decide to learn how roses from those classes fare in your garden, I suggest that you plant them where they get good air circulation and, ideally, full sun only during morning hours. Even when they're not in full sun all day, they still require more water than do most roses in my garden. Also, I've found that they're comparatively heavy feeders. They seem to do best in a rich soil, and they definitely respond quickly to fertilizer, which I apply in very early spring and again in early autumn.

I no longer grow any HPs, but still have a few Portlands -- 'Rose de Rescht', 'Marchesa Boccella', 'Comte de Chambord' (all of which I've had for a number of years), and 'Portland from Glendora' (given to me as a rooted cutting a few months ago). IMO, these roses are quite sensitive to soil pH (especially 'Marchesa Boccella'). If your soil is even slightly alkaline, do what you can to lower the pH, even if it's only to use MirAcid or a similar acidifying fertilizer. That was a lesson I learned over time after installing raised beds using "imported" soil.

My final observation is to say that in the spring of 2011, my Portlands performed better than ever before. I'm attributing that to the fact that the 2011 season followed a prolonged winter chill. The winter of 2010-2011 was the coldest, by far, that I've experienced since I began gardening here. If their spring awakening was any indication, the Portlands luxuriated in it.

I'm in zone 7A (Knoxville. I'm not sure if you're in Western or Eastern SC. I grow quite a few HPs and Portlands and they do really well for me. My soil is heavy red clay and our main disease issue is blackspot. They do blackspot a bit here, but nothing I can't live with (at least they don't defoliate).

Of the ones you mentioned I have these:
Rose de Rescht: great rose and very little black spot.

Souv du Dr. J: Not a favorite. Mine is own root and a
VERY VERY slow grower. Its 2 years old and no bigger than when I planted it...6 inches.

Leda: Highly reccommend! Healthy vigorous...doesn't repeat like the other two, but still well worth growing.

I'd prob cross post your question in the Antique Roses forum too...lots of long time knowledge there :)

Hope this helps, Tammy

Thanks Tammy, I'm right in the middle between florence, sumter kershaw, and hartsville(darlington county) is closest only 10 minutes away. wish souvenir du dr jamain was more recommended, loved hoe he changes colors, everyone so far has said he was a slow grower but two years is along time with no growth. my soil is sandy on top and clay beneath so I amend with peat moss bonemeal, ect. thanks for all your help.

The local botanic garden grows Souv du Dr. Jamain. It's a compact rose there, lovely blooms. It does have a unique color to the blooms. I don't know how old their plant is...

Munstead Wood has a similar color to Souv du Dr. Jamain, thought I'd mention it in case you like modern hybrids.

It have a beautiful fragrance.

RE: Really love HP's, and portlands

I've only grown one HP--Mrs. John Laing. I mention her because when I was researching HPs, I was assured that Mrs. John Laing was one of the more disease-resistant HPs. If that is true, then I think you are going to have some serious BS problems with your HPs. Mrs. John Laing is usually my first rose to get BS--not that she is a BS magnet, but I would rank her as only slightly above average in terms of BS-resistance--so I'd guess the other HPs have lots of BS problems in comparison.

If you want to consider Mrs. John Laing, she has really beautiful, full, fat blooms -- lighter to medium pink. She's a bit on the tall side, for my garden anyway--maybe 4-5 ft tall.

Can't help you out with the others--sorry.
