Along with Dianne in Idaho we won the CRS auction plant and photos have been posted. She has that plant and I have a plant budded on multi flora from bud wood from the auction plant. This variety has surprised me a bit. It’s not a weak grower, in coastal NE Florida it gets tall, tall and narrow. It’s also rather thorny! The spring bloom is gorgeous (see my photos) but in the heat of summer the blooms are single or close to single! And I own almost all old ARS annuals and reviewing the Proof of Pudding reviews from the mid 1950s (Roses in Review was called P o P for years) those in very warm climates noted that weird trait! That’s how I am certain this is the real variety that I’m growing. I was almost questioning it because I don’t get any damask or old rose fragrance at all. I get little fragrance. Almost none. Blooms are always on single stems long enough to cut. Repeat bloom is fast. It doesn’t blackspot or otherwise have disease more or less than the bunch. It’s a nice rose. A bit nondescript. I prefer 1944’s Mme Chiang Kai Shek as far as mid century yellows go as that variety is a bit more distinctive in my opinion and never blooms as a single 5 petal blossom (I’m not a huge fan of single blooms). I’m always happy to share plant material when I can so let me know this summer if this variety interests you.

In the absence of any data, I'd conjecture that this rose is a product of a breeding line that started with HP 'Frau Karl Druschki' and entailed several generations of seedlings of seedlings being crossed with yellow Pernetianas, HTs, and each other such that the only defined classification that any proportionately major ancestor had was the HP designation of the founder of the line (which I'm theorizing was 'Frau Karl Druschki').

Theory #2, which could be valid simultaneously with Theory #1 above, would be that perhaps the manner in which it blooms and/or grows seemed HP-like (or at least not HT-like) to whoever first classified it.
