of this plant are usually white, but
they can be of almost any colour.
Description: Very large and spiny cactus,
solitary or branched. The body is almost concealed by the spines.
This is a very variable species especially in shape and and length
of spines and in flowers colour.
Since the various forms
are connected by intermediates it is
extremely difficult to recognize
Stem: Bluish-green, spherical at first and later sort
of cylindrical, and it may grow 25 cm tall and 10-40 cm in diameter.
Ribs: 25 to 50 ribs deeply incised between the tubercles, which

summer-growing species that offers no cultivation difficulty. Water
regularly in summer (but do not over-water). It needs good drainage and

fertilizer in summer. It is quite frost-resistant if kept dry (hardy to
-5° C). Outside full sun or afternoon shade; inside it needs bright
light, and some direct sun.
