Bump. Come on folks, help out here! Jeff Bee needs our help!

Moses.

A less blurry picture of the blooms might help.

It looks very much like 'Sunny Sky' Eleganza or 'Winter Sun'.....such pretty yellow roses!

Moses....I also grow 'Oh Happy Day' and in its second season in my garden, it's beginning to put out some stunning blooms! Mine are a little more formal looking than the one's in Jeff's picture.

Same here, Roselady. Mine are almost exhibition quality....certainly the most classic hybrid tea bloomed bush in my garden, and it's ADR, too. Black spot, which is heavy here, does not appear, even late, like right now, on Oh Happy Day. Ya-Hoo!

Moses.

In case it helps anyone with i.d.ing it, the OP also posted the same question and pic on the NGA rose forum last week. Today (on that forum) he said that "it's grown in a park in Beijing (together with Double Delight, Peace, Tiffany and so on), it should be a relatively old variety". He also said that it was not fragrant.

That's very helpful Susan. Now I'm wondering if it's 'Elina'.

My first thought was Elina, as well. But while the bloom resembles my Elina (a lot), the foliage doesn't match. The leaves on Elina are more rounded, and don't cup under like this one. Of course, the cupping may be related to growing conditions. Also, Elina's leaves are very matte, not glossy at all.

It's hard to tell from the photo, but my Elina has always reached at least 4' by midsummer, sometimes 5'. This rose seems much shorter, but the OP doesn't specify if the photo is Spring/Summer/Fall (although from the pristine look of the foliage, I'm guessing Spring). Its short height could also just be a result how severely they prune, lol.

@Jeff Bee -If there are any other photos that might show buds, that would be another clue. For Elina, the first few petals to open are almost pure white, while the center of the bud remains creamy, butter yellow. In very cool weather, all the petals will be yellow as they first open, but very soon the outer petals turn white.

fig,

Elina was my rose mentor's favorite rose. It won an ADR when it was first introduced and although not 100% black spot proof here, it is one exceptional rose. I should grow it, but my experience with yellows has been that the blooms are very fast to go to petal drop, so the Elina with which he gifted me went to a devoted rose gardener friend. This was a number of years ago.

Moses.

One thing I thought was interesting is that if you look closely, a lot of the leaves on the surrounding roses look similar. And just a tad odd-ish. Fertilizer... climate? I have no idea what Beijing's climate is, other than being known for very polluted air until recent supposed improvements. I grew Elina for >20 years, and I could see it being Elina. @Jeff Bee, can you come back?

@Moses, Pitt PA, cold W & hot-humid S, z6 Moses, Elina is wonderful here, easily in the top five of all my yellow roses. For a yellow, she is quite robust. But she is NOT blackspot free, just "fairly resistant". Most of the rest of those top five yellows would be Ping Lim yellows, lol.

The subject of this thread definitely has Elina-like blooms. If it's NOT Elina, I don't know what it might be (and I've grown wayyyyyy too many yellows, looking for good ones).

And yes, even as good as Elina is, petal drop is fairly quick once the bloom is fully open.

Yes, I'm brutal on yellows....if a yellow in question is not just about perfect in all regards, I don't want it. I know I shouldn't be so hard on yellows, but yellow is my least favorite rose color. I got rid of my Julia C.s because of black spot and short bloom life.

Moses.

Susan,

I think that abnormal looking foliage is early signs of powdery mildew. At least in my garden, when I see that strange looking curved-in foliage, I know the powder formation is not long off.

It could also be a recent sudden but critical slacking off of watering, just after the roses reached their peak of bloom, so the blooms don't look stressed, but the foliage does....just a thought. The soil surface in the lower right of the photo looks pretty dry . However, the foliage is otherwise pristine, no nutritional shortages seen, nor any insect damage.

Moses.
