I think alot of people will say Julia Child. She is very disease resistant and a real bloom machine.I think in your zone she will stay within your size requirements. I also have carefree sunshine, but Julia is my favorite.

I have had good luck with Shockwave in a pot this year. The other yellow that I have that blooms the most regularly is Golden Fairy Tale, but it is bigger than what you might want.

I would recommend "Sunsprite". It is a nice lemon yellow and has been a good bloomer for me. Honey Perfume is another great one, it is constantly in bloom and has an amazing fragrance. HMF says it is apricot in color but here in my climate it is much more yellow. I have Julia Child but am over it, the blooms fade very quickly(though in its defense Julia does bloom a lot)and it is more of a dull butter yellow.

Julia Child of course ; )

Pauline I don't know about April but I'm sold on Amber Queen:) May I ask where yours came from? They're grafted?

Thank you.

Kate

YIPPEE!!! I have one ordered for this fall and now can't wait to get that baby. Don't know what its grafted on but I ordered it from Palatine a couple weeks ago because everything I ordered from them last spring did great and the size of the bareroots were great. Can't wait for those purty blooms. Judy

Julia child for sure!

Honey perfume is not really yellow and for me it does not have a scent at all. Many people say that, but I do agree it is literally covered in roses constantly.

Another vote for Julia Child. Ours was eaten from the bottom by a gopher and looked totally dead overnight. My husband put gopher poison in the hole, closed up the hole, firmed down the roots and, lo and behold, it's putting out lots of new healthy growth after not having had a single green leaf on it. What a rose. It's also the right size with healthy leaves and golden yellow blooms.

I like Honey Bouquet. The bush is covered in soft yellow blooms all summer and I much prefer it to Julia Child, which I also grow.

I am ordering Julia Child from comments and pictures.

My Sundance has hardly ever been without a bloom this year and this is only its second year. They last a long time and do not fade very much at all. I've been very happy with it.

WOW! Thanks for all the suggestions! Now I'm just gonna have to add SEVERAL different yellows to see which I like BEST! I shoulda got JC when I saw her earlier this year. Ah well, she'll come around again. I actually found three yellow mini's today at a nursery and went ahead and snapped them up. I have NO yellows in my front yard so I thought i'd add some in with my beloved pinks. I MAY even add a few PURPLE. Now that's something I thought i'd NEVER say! LOL! I've always like purple perennials but not so much in roses but i've saw a few lately on here that just might be changing my mind! Thanks again for the great suggestions! April

Julia Child - My has only been in the ground since June here in CA and it has bloomed 3 times already very heavily. I am very happy with it as it's foliage is top notch and no sign of any problems. I'll be getting another one for another part of yard. Seeing it full grown and all the info here convinced me! The multiple colors of yellow as the blooms age is quite lovely I think when all put together. It's one of my favorites. Hope you like yours as well.

Emmie, do you mind saying what area you live in?

Carla

April, I apologize for hi jacking the post.
Emmie, which hybridizer is your Sundance from?

Carla

No problem Carla....just happy to get some response! Posted a few pics on the gallery and hardly any response over there. Guess folks like to make suggestions more than they like to gaze. lol. Maybe they feel like this friend we went to the Colorado Rockies with one time. We rode ALL the way from Georgia to Colorado and we get there and he says... "well, you seen one mountain, you've seen em all."" And was ready to turn around and go back home!!! Can you IMAGINE that kind of outlook??? It's become somewhat of a joke with us now about everything. SOOOOO I guess you seen one rose...you seen em all!! Hehehehe. Definitely NOT true with roses NOR mountains! Okay....i'll try to get BACK on subject here.... YELLOW ROSES......

Kate My first Amber Queens were ordered directly from Harkness per an order from me. It was a fabulous nursery, but we no longer have it unfortunately. The last one, I purchased either through Pickering or Hortico, I am not sure which now! It is the colour yellow, that I like - very like Golden Celebration colour but glows a little more. Good Luck, I hope you get it and like it too!

I am sure the most popular one here, Julia Child is delightful, I cannot see me getting it though, only because I have a lot of yellow now. I also have St. Patrick and three Golden Celebrations. I was never even a yellow person, but I do love all these bushes.

Cheers, Pauline.
