Stays relatively small and compact with stunning, very sharp spines. These two photos are of the same plant in different lighting. Above, in full, midday sun, and to the right,
the blue glow in the early morning.
Very easy plant to grow.
This one is in a pot with two pups.
It is probably root bound.
Water when dry in summer and
occasionally in winter.
Does well in full sun but appreciates a bit of shade in the hot, later summer sun.
