they may look similar, but the 55 Flowery was developed by a breeder, and the Swedish Flower evolved without breeders in southern Sweden (and there is an organisation in Sweden to try to preserve it) so their genetics are probably quite different.
I can't speak to 55 Flowery, but Swedish Flowers form the core of my flock, and I love them. I have added several other breeds over the years, but the SFH are my favourite. My oldest roo (my avatar) arrived here supposedly a pullet in 2018. He's still here. My oldest hen (came a month later as replacement for the other roo I got in first batch) likewise. Re: petting, I don't handle my birds unless absolutely necessary - they free range dawn-dusk and my philosophy is to let them live as naturally as possible. He survived a fox attack in 2020, and during his recovery learned to trust me. His son took over as dom, and he's been a subordinate since. Currently he's being harassed by 3 young roos, so comes in to feed in peace, either hops in and walks to the utility room or stands by my legs and I carry him. Meanwhile (despite her age) she laid over 120 eggs last year, 6 of which were set under a broody, 5 hatched, and all are thriving; 3 laying, 2 either laying and hiding their eggs or yet to start laying. This is 3 of them on bug patrol last November.
