Description: It forms large low
clusters of white textured monstrous and crested
stems, and the plant looks more like
some non-cactus
succulent than a
cactus. These plants show different crested and monstrose shapes.
The
cause of monstrosity and cristation: The cause of anomalous form of
growth is not fully explained.
Biologists
disagree as to why some Astrophytum grow in this unusual form. Some
speculate that it is a genetic mutation. Others say it is the result of
a lightning strike or freeze damage, but whatever the stimulus, the
growth point of the stem has switched from a geometric point, to a line,
which folds and undulates as the crest expands.
Though these crested
cacti are somewhat rare (1 in 50,000 or less), cresting occurs naturally
and can be encountered in many
other cactus species.
Cultivation: Astrophytum myriostigma
cv. ONZUKA forma cristata mostruosa grows well on its
own roots. Keep well
ventilated, as it is prone to
root rot. Protect from
frosts and
freezes. It hates the sun.
Propagation: Grafting (usually) or by cuttings that
hard to root.
