The Fan like Dyckia is a beauty and soon red ones will appear.

Described as a species this plant proved to be extremely problematic in setting seeds

This goes up to the point of being totally sterile.

This in fact is a natural deformation, a chimerism, and the very same reason for this to happen also turned the plant sterile.

This is a true and legitimate Chimera.

A beautiful and too fantastic plant derived form a normal looking one the one that produces viable seeds that turn to be fan like and normal formed seedlings.

Your fan Dyckia doesn´t set seeds not for being self unfertile but for being

completely sterile.
