I grow South Africa. It is pleasing me quite a bit. The blooms are large, a rich golden yellow that holds its color in the sun. Although I am technically in zone 6, I like to shoot for bushes that are listed hardy to zone 5 to insure cane survival to at least half their length over winter. I don't winter protect my roses. South Africa has been dependably hardy so far, but it is not yet mature in my garden. The two I grow are own root, three and four year olds, and got hit with a severe winter in 2022, which they took well enough being youngsters. They should reach about 4' by season's end when mature, maybe 5'. South Africa is a robust bush, growing single bloom and candelabra canes of about 9+ booms, being a true grandiflora in growth habit.

erasmus, how does your Golden Celebration do with BS? I've always wanted it but am afraid of how it will handle a no spray situation.

I recently saw a very pretty yellow that was holding it's color and looked healthy At A. Regional garden a couple hours north of me. Sweet JaneJane It seems Quite a few people are growing it in varied Climates including Chicago That's any indication of it's hardiness. I don't know if they spray but it was clean.

Caroline, I'm in the NC Piedmont too. I don't think Golden Celebration would do well no-spray.

Another good old yellow is Autumn Sunset. It's healthier than GC, is supposedly very fragrant though I can't tell, and is hardy in zone 5b.

South Africa - it does fade but it starts out strong and is fragrant and healthy. Some say it has a lot of vigor.

I also grow autumn sunset and can attest to it's health and beauty and fragrance! Erasmus , I would love to see any bush shots of your autumn sunset if you have any At your convenience Also like to know how you take care of this for best bloom if you have any hints.

S Africa is super healthy in my garden, but I am not a big fun of her. Sometimes she looks cabbage like, sometimes very simple as it now.

Vapor, I really don't have any tips. I have not pampered it. It toughs it out. Here's a whole plant shot, such as it is. I don't prune hard to keep plants small.

Here's another yellow that might be hardy enough...Golden Century climbing mini bred by Ralph Moore.

My plant is only a year in the ground but is vigorous. See Paul Barden's amazing, huge plant of it.

There are other wonderful pics of it on hmf as well. It says it's hardy from zone 6b, but it's possible it would be hardier than that.

Golden Celebration stronger color...I like the buds:

Sweet Jane looks like a good one. Another yellow I really like is Sunny Side Up.

Thank you, erasmus. Your GC is stunning.

Thanks everyone for the recommendations and for sharing your beautiful pics. I'll have to check these out.

Thank you! Yellow is so cheery. A couple of others that according to hmf are hardy in zone 5:

Ghislaine de Feligonde

Buff Beauty...can be yellow

Or more apricot/ buff

I've seen a beautiful Buff Beauty covering an arbor.

Oh, wow...I just looked up Alister Stella Grey on hmf and it says it too is hardy in zone 5. Alister STella is so healthy, so vigorous, has such great rebloom and to me is very charming. I've seen a great picture of a huge one in England blooming against a house.

I don't know if you're looking for big, small, or what.

Mine is not a house eater in zone 7a, and quite likely in zone 5it wouldn't be either.

Funny thing is that I used to avoid yellow roses because thrips & bugs loved them . But I am tired of all white/ pink/red and am looking for a good yellow too . I am growing Midas Touch this year , I like the deep yellow color but the petal count is low and blows open quickly to show dark colored stamens which I dont particularly like . Also growing Sunsprite this year , small pale yellow roses .

I used to grow :

South Africa : was a stingy bloomer . Kordes Winter Sun :bloomed a lot of pale yellow hybrid tea roses, loved it but thrips loved it more ! Kordes Sunny Sky : lousy blooms on octopus canes . St.patrick : Black spotted & got thrip damage on beautiful hybrid tea blooms . Julia Child : bloomed a lot but blew open quickly and black spotted .

I love those Graham Thomas photos. Makes me want to try it again! I have been wanting an Alister Stella Grey. What a beauty! I had no clue it was that hardy. Of course, hardiness isn't my issue here, blackspot is lol.

The healthiest rose I have, thats been listed here, is Teasing Georgia. It has been a really solid rose. It ranges from yellow to gold to rarely peachy (only in cold weather). Gets huge though...like 14-20ft. Might not be so aggressive in a colder climate.

@bellarosa, I have a Golden Opportunity which is child of Julia Child. It is a climber with similar color, bloom shape and scent but healthier. It is its first year though so things might change

The blooms are a bit loose to my taste

I like the blooms of Graham Thomas better, but it is such a BS magnet in my area after spring. Still its spring flush is hard to beat. This is his second year
