I'd consider 'Sally Holmes'. Very disease resistant and with nearly continuous blooms.

Finding a selection of roses in fall may be difficult. Most places are sold out. Late winter to early spring is the primary selling and planting time.

Dmitri is wonderful! You also might want

to look at Alaska. I don’t have it het but I’m hoping to get it next year

I grew Arborose Honeymoon at my last garden and have a new baby one for my current garden. in my PNW location it’s disease free but it did take a few years to really take off and bloom reliably. If its hardy for your zone I would highly recommend it though its not fragrent to my nose. Looks like its in stock at Heirloom if you want own root and you want to plant this fall.

Thanks for the input. Very helpful. I love both Dmitri and Alaska but the specs say they grow to 5 ft. Is that a conservative number or do they grow longer? I am looking for something closer to 8 feet.

Dmitri is brand new this year and already over 6 ft and Palatine has Alaska

at 8-10. Not sure about your yard but climbers almost always exceed size expectations here

Honeymoon is a beautiful rose Mine is only a year old, too soon to comment on height, but so far i really am pleased with health and repeat.

Next year i want to try Cloud 10. It looks like a good one…

Another wonderful white climber is White Cap, It’s an older Brownell rose. and blooms like crazy for me.

If you like singles, Darlows Enigma is so easy for me. I let mine get shrubby but you can keep it thinner. It does have lots of thorns so not good for a walkway, but a rose i wouldnt be without.

Good luck with your selection!

Madame Anisette, 3rd season on her own roots in my garden. She is not marketed as a

climber, but it would be very hard to grow her as a shrub in this climate. In her 2nd season I tried pegging her super tall canes and got tons of bloom filled laterals but she still wants to climb. So....in August we built a arch for her.

First flush this year after I cut about 4dozen blooms for a wedding

I didn't keep up with dead-heading this year and she's still reblooming decently while setting huge hips. I just took these photos today.

In the fall she's more blush.

Great vase life, blooms last long on the bush and I love the anise biscotti fragrance. Very very healthy.

Our not very elegant emergency trellis. I doubt we'll even see the trellis in a year or two. She's very vigorous.

IIt's a cattle panel we turned into an arch.

@librarian_gardner_8b_pnw

Librarian your Madame is the most beautiful ever. Couple you please share a picture of the entire trellis if that’s ok? I have used some of those panels for trellises against my shed but haven’t made an arch. Were you able to use a single panel or two tied at the top?

I'll take a picture of the whole arch tomorrow if I can 😁

We used one single cattle panel and it's tall enough for my 6'4 husband to get through.

@librarian_gardner_8b_pnw Amazing pictures. I am concerned that the Madame will not climb tall enough for my needs but it is beautiful. I need something that will go at least 8 feet to lay on top of my trellis.

Hi Jim, if I hadn't pegged it last year, it would be mucj taller this year. I'd say it's near 9 feet at it's tallest new growth this year. I'm pretty sure next year I'll be training it up and over the side of the arch early next year. In my zone I think there is no problem having it reach 10 feet. It's only not that tall yet because the first two years I grew it I kept trying to make it be a shrub.

I can measure it this evening to know exactly how tall it is 😁

Dianela, how tall does yours get?

one of my Madame Anissette On a 10 feet obelisk. She gets taller than that (probably 12 feet or so if not pruned).

Jim the size vendor posts on their website for roses is something you have to take like a grain of salt. Most Kordes get way larger than what they say unless you live in a very cold region. I do not know if where you are is zone 6 or 7 but Madame should get large enough for 8 feet. I am on 7b but due to being higher up we get to the single digits regularly during the winter with zero cane loss on my Madame A.

I would also love to try Alaska as whites are my all time favorite roses and they are hard to find with full blooms and great disease resistance.

I have Honeymoon and it seems very healthy and has gorgeous blooms but it does not seem as vigorous as my Madame A which is a monster.

I also grow Cloud 10 and it has beautiful white blooms with a warm yellow center when it first opens and perfect blackspot resistance. It has stayed at around 6 feet tall here so it may have a harder time climbing high but you never know until you try it.

Dianela, not trying to butt in here sorry, but I have arches made from almost the same materials and they work pretty well for me. However I find that without support along the actual arches part, they can bend under a lot of weight. I've never had a plant bend one, but I have had snow do it. I was able to mostly reshape it but it's a little wonky now 😅

@Mischievous Magpie (CO 5b)

Mischievous I love your arches. We do not get any significant snow here (usually 1-3 inches a couple times a season, we just get lots of slippery ice). How do you support the curve of your arches?

Since this is OT I will start another thread asking for structure ideas. I will start a new garden in the near future and want to have a lot of structures.

Jim, I think fall, winter, and spring are a good time to plant. I plant a lot in fall and on into winter if I don't get it all planted in fall. I think they settle in during cooler weather and are ready to take off in the spring. I like to plant when they won't be heat stressed and when more water is in the ground. I'm in zone 7a, NC, and winters are not very harsh. When I plant in fall it's gallon + pots usually , not brand new babies. They've been putting on size during the summer. Don't think I'd plant a greenhouse grown new rose in fall unless in a mild climate.

Here's my Madame Alfred Carriere. If you want to be sure you have a vigorous one this one is vigorous but it will overwhelm a small arch.

It was on a smaller arbor but outgrew it. My husband built this bigger structure and the rose ended up going over that way. It reblooms, is mostly healthy, is not very thorny, has a great fragrance, and is supposedly pretty hardy. Blooms are mostly white but can have a blush of peachy pink .

Madame Anisette looks wonderful .

Here's a picture of the arch and Madame Anisette with tall canes that need to be tied to it. I'm 8 months pregnant right now, so I guess that won't be happening soon. 😅

The tallest canes are definitely more than 10 feet tall and they're all new growth since this spring.

Another couple of whites you might consider are Sombreuil and Cl. Iceberg. Jeri Jennings has a wonderful Sombreuil on an arch, and Mendocino Rose had a great Cl. Iceberg on an arch. I have a nearby rose friend who had a big Sombreuil going up to the eaves of his house, and it crossed over to a play house on a ladder-like support so it covered a lot of territory.

Sombreuil...it's fragrant but mine was not blackspot free.

Penny Lane....mine's in a tough spot so I don't think I know how vigorous and tall it can get but it's pretty and pretty healthy.

Jacqueline in CA has a humongous Madame Alfred .

Sally Holmes is pretty and vigorous. In my climate it got some blackspot and to my nose did not have much fragrance.

Madame Anisette looks hard to beat and it sounds pretty darned vigorous.
