Cactus / Hanazono kabuto

This is an Astrophytum asterias cv hanazono kabuto. Hanazono means a flower garden and this cacti has multiple flowers. Although the histories of super kabuto and miracle kabuto are quite clear but it is unclear for hanazono kabuto. It seems hanazono character will appear when the caci became mature age. When the cacti was young seeling, the appearance is same as a normal asterias.
