I agree. While insigne had many forms, most of which are long lost, this looks like a hybrid. Just saying. With so many complex being made and distributed, many of which unfortunately without tags, there are surprising number of things that are shockingly similar to species or primary hybrids. I knew about this but was shocked to see it first hand in Europe, Portugal to be specific.
In the US, breeders focus on awardable flower shape, so often, those round flowers are around in the market. On my vacation to Portugal, there were vast array of shapes and sizes of these complex hybrids. None of them had tags.
