Cactus / ruri kabuto

Astrophytum asterias cv oibo ruri kabuto was in flower yestday.
Ruri means lapis lazuli.
When the plant was matured age, the body color turns to lapis lazuli color and so this cultivar is called ruri kabuto.
Ruri kabuto is not a normal asterias v nudum.
It is told the gene of capricorne v major is mixed in history.
I bought seeds and sowed on 17/09/2004.
