Star Roses lists this as a Floribunda on their website

Of course Meilland categorizes it as a Grandiflora in the patent, but then goes on to list the average height as between 80 - 90cm.

I don’t know the height specifications for a Grandiflora, but I always considered them taller than HT’s, at least over 1 m, but I could be wrong.

The definition of ARS states that Grandifloras are HT-like, but cluster-flowered and grow to 6-8 feet or more. The breeder has patented this rose as a Grandiflora, but it is old as a Floribunda. It's seed parent 'Centennial Rose' is also a declared Grandiflora despite having a height of only 2-3 feet.

The ARS is slow and antiquated. In the US, and those that have bred for US releases, have a few models for what a grandiflora is.

The original model is the tall one, as described. Queen Elizabeth would be typical of this. "Stately," as they say.

Then, there are the quite round ones with large sprays and large blooms. Tournament of Roses and Sunshine Daydream would be typical of this. .

And then there are the "flori-tea" types, that have a small cluster of moderate-sized blooms on a medium height plant. Sonia, Caribbean, etc. are this type.

Of course, there is overlap and confusion. Its a really faulty system of classifications imo. Although, it seems that most breeders simply consider a grandiflora to be a bush rose with 3.5 to 4.25 inches in width.

Roses like Silver Jubilee and Colorific break the system. Not to mention many, many florist roses.

IMO, I would consider Sunset Horizon a large-flowered floribunda. It behaves that way in my garden, at least. Playboy has similarly large blooms, despite having few petals. In another system, we could be less subjective about the topic.

High Country Roses is also calling it a floribunda, which it probably is in zone 5. Stunning colors. I might order one if HCR has their fall sale this year.

HC lists Sunset Horizon as a Floribunda (Alain Meilland, France, before 2018). Website says it's 2-3'H x 2-3'W, semi-double, yellow blend.

Color finished to almost all dark red, with some white at the base where sun didn't touch much, last year.

Honestly, its a lot like Playboy, but also different enough.

Edit: Its been a bit so I can comment more.

It doesn't have an orange phase like Playboy does. Its just straight from chrome yellow w/ red highlight to a crisp red w/ silvery white where the sun never touched after a few days. It is also more linear in habit than Playboy is. Health is still relatively similar for my climate so that is good. Foliage between semi-glossy and matte vs. very glossy in Playboy. Seems to bloom in heat just fine, so blooming seems to be unaffected by whether it is very rainy or very dry out.
