I am new too :-)
No, this cactus was not bred by Hanazono.
Hanazono is the name for one of the many Astrophytum asterias cultivars:
"Some additional woolly areoles are produced on the ribs surface. Flowers buds develop from the median line between two ribs and usually they are not produced by areoles."
Have a look at this web page. I love it!
Up here I find only very few cactus species and always and everywhere the same species too. If your nursery does have them, please let me know.
