It could be the Kordes ADR winner, Oh Happy Day. The flowers appear to match, and the pristine foliage is a strong indication that I could be right. I grow it myself and it is a keeper so far, second year in my garden.

Moses.

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.

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.

OMG thank you so much, guys!

sorry for the later reply，cause I have to use "special techniques" to get to the websites outside....I often forget to check about the updates...

the video is uploaded to Youtube for your reference: https://youtu.be/B0qZ3tmeiik

sadly,I only have this 14 second video, so not much more detailed information can be provided.

I'm from China, the rose is from a public park in Beijing together with Double Delight, Peace, Tiffany and so on, it should be a relatively old variety(and the rose bloomform is also old-styled because of the big petal shape and low petal count) (so i don't think it is Oh happy day or winter sun or sunny sky, they all seem too "new" styled)I will try to go to the park this ring again to try to ask for some more information.

it's not very fragrant to me.

the photo is shot at 18:00 pm of May 20th, almost sunset so the light was not good

in Beijing during late May, the weather was super hot and dry, the sun is burning during the day, that's why the earth seems quite dry.(so maybe the leaves are curly because of water dry)

I also doubted about Elina，but most elina i see in beijing have semi matte leaves which is not so glossy as in the picture

I also doubt about "apricot nectar ", which have similar color and bloom shape and also the leaves are more curly and glossier than Elina. but the information on internet about the apricot nectar is so little，so i'm not sure....

some other info

some popular yellow varieties in China are listed for your reference:

• Candlelight(tantau)
• Beatrice(DA cut rose)
• Poet's wife(DA)
• Catarina (cut rose from Dümmen Orange, some say from Japan ）（this one is super bright yellow）
• Sunny Antike（Kordes）
• Shining Smile （ シャイニングスマイル , from Japan）

(Chinese customers put more emphasis on the bloom shape and prefer compact short bush)
