Not many good yellow climbers I know of. However, look at:
Skys the limit
Golden Showers
I can also recommend Autumn Sunset, which is not quite yellow, but more of a yellow/ orange. This is one of my favorites.

Zeus! The flowers are true yellow, the color lasts well, the foliage is good (with my biweekly-or-so fungicide spray program), and it blooms well.

I have a few other yellows on the arches in the Rose Field. They are all climbing floribundas. This is their second year in the ground, and they're not quite climbing yet. But they survived the winter, they're growing, and they're blooming.

Climbing Allgold
Climbing Goldilocks
Climbing Yellow Sweetheart

Of these three, Allgold is the yellowest and it fades the least. Yellow Sweetheart fades to cream color pretty quickly. Goldilocks is in between. They all have been blooming fairly steadily.

I assume you want true yellow, instead of the almost-yellow of the Tea noisettes. Reve d'Or, Georgetown Gateside Yellow, Phil Edinger's Noisette, and Alister Stella Gray come to mind.

I also have Sungold and Le Reve, but they are new and I don't know enough to recommend either of them yet.

This should give you something to think about.

I am pretty pleased with Sky's The Limit.
She has been one of the more healthy roses in my garden this season.
With all the moisture we have had,
she hasn't got BS, canker nor Botrytis as many of my other roses have.
Her leaves are thick, green and shiny.
In my zone, her 3-4 inch blooms open yellow and age to a creamy yellow/white.
She had a little die back, but not too drastic.
I would have to she is a 5 out of 10 on the scent level.

Cool! I've never heard of Casino before. I just checked it out on HMF. Nice flowers!

Another I've encountered before is Royal Gold, but I don't like its flowers. Their color is good, but I think they only look nice while in bud. I don't like the form of the open flowers at all.

I'm very interested to read this thread - for years now, I have been trying to find a beautiful and reliably hardy yellow climber! (I do grow - and love - Autumn Sunset, but to my mind he's more of a yellow/apricot. What I'm after is a real golden yellow). Casino and Zeus both look good. I got Sky's the Limit last year, but have not been too impressed. He had some die back, and has not put on much of a show so far this year. Although I realize I do need to give him at least another year before I decide. Another one that was suggested to me was Lichtkonigen Lucia (sp?) - I thought I might try her next year. But now, I'll have to also consider Zeus and Casino ...

Get in line..... ;-)

Another one that was suggested to me was Lichtkonigen Lucia (sp?)

That's a Kordes rose, so the name is German and the 'o' is umlauted. That means there are two ways of spelling it, one with the umlaut ("Lichtkönigen Lucia"), and one without ("Lichtkoenigen Lucia"). "Lichtkoenigen" means "Light Queen".

The pictures at HMF don't show much besides blossoms (a common problem there, in my mind, despite my fondness for that website). I wonder how much of a climber it actually is?

I have seen Austin's The Pilgrim grown as a climber...

What about Malvern Hills (Auscanary)? It is in the Austin catalog but no one mentions it. Has anyone tried it?

You might try Lemon Meringue, which is a sport of a sport of Westerland. Ours got up to 10 feet this year--but it is really in Zone 7--right next to our furnace chimney. There are plenty of buds on it for its 2nd flush.

Here is a photo of Lichtkoenigen Lucia taken at Vintage. I don't know how old the plant was but it definitely was upright and the foliage so dark and glossy it almost looks waxed and polished which gives the plant a very modern look.

Take a look at Climbing Carefree Sunshine. I am getting good reports on it in the NJ/PA z6 areas (Frances, may be worth a try).

york rose is almost correct about the spelling, but it's actually Lichtkoenigin Lucia, i.e. it ends with "in" instead of "en". Not that the rose cares in the least....

Licht...what?

Thank you everyone for the suggestions. Now to narrow them down to 1, 2, or perhaps 5 or 6. :) This exercise has gotten me interested in exploring a repeat-blooming Easlea's Golden Rambler. That would be an unbelievable rose. Thanks again. Best,

Nick

Here in Tropical Minnesota (zone 4a), two repeating yellow climbers that work for me are Brownell's Golden Arctic and the Canada rose by Fleming, Roberta Bondar.

RB has great HT form and good fragrance. GA opens to a very full, powder puff like bloom with good fragrance.

Both are crown hardy here with just a light wood chip mulch for winter protection. Even though they freeze to the ground each winter, they have enough vigor to regrow to a respectable size. They will reach five to seven feet by fall.

Regards,

Charles
