Concerns about heat tolerance.
User Ericchn has provided some breathtaking pictues of Raspberry Cupcake looking absolutely great in "the heat wave of 34°C in Madrid". However, different youtubers and forumers share experiences of Raspberry Cupcake being burned and fried in the Sun with the roses growing right next to them unaffected.
More people should weigh in on this issue.

I've had no experience with it apart from considering buying it because it looks quite appealing, but all I'd say is that I wouldn't consider 34°C particularly hot, and that no doubt ambient humidity must play a part in a rose's performance in any heat.

Please take into account that this variety won at Madrid rose trials in 2019, which means the testing plants were planted in autumn 2017 with a constant dripping system. By the time I took these photos in May 2022, these plants were already well established in the ground with constant and enough water supply, whereas I don’t think it’s the case in US as “Raspberry Cupcake” was only released in 2023.

Following on from a discussion started under a photo posted by Pauline M (id 376193 15 Oct 21):
A couple of days ago I saw potted Black Boys in a local nursery in Sydney. Only one flower was out at the time, a large, somewhat loose, red bloom with black shadings. Knowing that there have been some impostors offered as 'Black Boy' over time I was hesitant to buy one before I looked closely at the file photos here again. I admit I became a bit confused since there seems to be quite a difference in the appearance of the flowers. So I went back today planning to buy one and try it out and observe it over time.
The same plant with the one large flower was still there but another bud on that same plant, that hadn't opened the other day when I saw it, was now fully open. What amazed me though was how small it was in comparison to the other older flower! I estimate the first flower was about 4 1/2"/12cm, but this newly opened flower was at best only about 2"/5cm. It was also quite different in form too being flatter and more rounded. Maybe it will expand more but I doubt it will get to the size of the first flower.
I then reckoned that if the flower appearance can vary so much on the same small specimen at the one time it must vary considerably more on larger plants at different times of the year, and in different growing conditions, hence a lot of variability in the photos here. Therefore, being a bit more reassured, I bought one to try out.

Hello Pauline M,
I'm curious about your 'Black Boy' and whether it is one of the roses from the old garden that you mention on your profile page or whether it was acquired more recently. I note that your specimen displays the rather jaggedly undulating petal edges evident in the two old black and white catalogue photos here and I'm thinking that if your plant is very old it's probably the correct one, or if it's more recent the nursery you bought it from has the correct variety. I've been thinking of getting a 'Black Boy' that I saw recently in a nursery in Sydney but I didn't want to get it if it isn't true, so I'm just interested in the provenance of your rose. Many thanks.

I'm wondering if comparison with its parent Bardou Job may be a good test of a true Black Boy. See Patricia's comparison photo in Comments on 11/10/14. Also my photo 238797, with a purple clematis. The distribution of the shades of red, and a small white eye.
You can see why people have suggested Bardou Job in the pedigree of Restless (which got the red eyelashes, though Black Boy didn't).

Margaret, I had noticed Patricia's comparison photo, and thanks too for your new comparison photo to 'Bardou Job'. I agree, they look very similar. The plant I saw in the nursery had a bloom exactly like Nadene's photo 361516 (27 Mar 21) which was bright red with black shadings, and the bud receptacle shape was exactly the same - long and rather narrow. I notice now on Pauline M's photo that there is a bud or two with the same long receptacle at the bottom of the photo. I saw on Ross Roses' website that their sole photo of 'Black Boy' bears a striking resemblance to the upper bloom in the Armstrong photo and I notice that one of the recent references was from Maureen Ross talking about a specimen planted in 1927, so I'm wondering if their stock is from an old known specimen.
I guess I'm just confused by how different 'Black Boy' looks in all the photos. I suspect it's probably a case of the real 'Black Boy' differing in form and colour throughout the year.

I've read of Guinee, Cl Chrysler Imperial and Countess of Stradbroke being labelled Black Boy.
I don't know if the rose offered by Ross Roses comes from Jean Reid's garden.

Margaret, I went back to the nursery and bought their 'Black Boy'. I'll post more about it in the general remarks section.

This is one superlative, strongly fragrant old Hybrid Tea. It would not surprise me if it was found that the famous 'Mme. Isaac Pereire' was a parent, or 'Tom Wood'?.. the scent is very similar at its best, and the rich pink fully double blooms have that look about them..

Marlorena, you could be right about 'Tom Wood' being a parent, or at least some similar H.P..
I just came across a reference written by Dr. O'Donel Browne about his namesake rose and (although he doesn't disclose the varieties) he says that he knows that it is a cross between a Hybrid Perpetual and a "pure Tea". He also agrees with you that the perfume is superlative.
I wish we had this one in Australia; I'd probably grow it for the perfume alone.

Oh that's really interesting to me Hubert, thank you.. I wonder what the 'pure Tea' was.. I wouldn't have guessed that.
