Many very different Astrophytum hybrids have
been developed involving
A. ornatum and are now in cultivation.
The superb feature of some of this hybrids is due to the intersection
between the traits of the ancestors and make them very desirable.
The more beautiful the pattern and the markings, the more sought after
the plant. Many of the best have inherited by “ONZUKA” very large,
white flecks with V mark. Ribs are sharp usually eight (like in A.
ornatum) and are spineless (or whit very short spines) clearly
indicating the relationship with A. myriostigma.
This hybrid are strong growing. The flower are also very beautiful.
Compare with the inverse hybrid which is
similar but with spines.
