I don't grow this rose, but I have seen it before. It's gorgeous! The picture in your link does look like Archhduke Charles. Some of the pictures on the HelpMeFind Roses website (one of my favorites) show blooms with visible yellow stamens (maybe the older blooms??)

I've wanted to order this rose myself, but have been afraid that it would not be hardy in my zone. I have planted a few teas in sheltered spots but haven't tried any Chinas yet.

Here is a link that might be useful: Archduke Charles at HMF Roses

Thanks for the link.
It says mild fragrance. Mine is SUPER fragrant with an old-fashioned rose scent.
Also, the rose petals on that photo of Archduke Charles are more pointed, whereas mine are more rounded.

Hmmmm...

Archduke Charles will usually have a nice strong fragrance. It is widely grown here, and sometimes the blooms are one way, other times they are a bit different; Cuttings in neighbors yards, from the same parent bush... I don't know why.

I love this rose, and it is so easily propagated.

Archduke Charles

"Prior to 1837
Thomas Rivers called this rose "changeable as the chameleon". The full, very shapely flowers open with crimson outer petals and neat pink centers, then darken to solid crimson. The heat of the sun speeds the process: what appears to be a bi-color hedge in spring and fall will be all red roses in mid-summer. The neat, erect bush and constant bloom help make this one of our most popular varieties."

Maybe chameleon is the key word.

It is so hot, mine are about the size of strawberries.
Come on Oct.

I love the two colors showing up at the same time. I see it is a China rose and the only one of those that I have been able to keep is 'Old Blush' that has no fragrance. I have tried without success to take cuttings of it.
